The correct answer is B. To find the oxygen saturation level, divide the current number of milligrams per liter by the capacity milligrams per liter: 6.4/9.5. Convert the result (0.6737) into a percent by multiplying by 100: 67.37% is approximately equal to 67%.

The oxygen saturation of a lake is found by dividing the amount of dis...
To find the oxygen saturation level of the lake, we need to divide the amount of dissolved oxygen in the water by the dissolved oxygen capacity and then convert that number into a percentage.

1. Calculation:
The amount of dissolved oxygen in the lake water is given as 6.4 milligrams per liter.
The dissolved oxygen capacity of the water is given as 9.5 milligrams per liter.

To find the oxygen saturation level, we divide the amount of dissolved oxygen by the dissolved oxygen capacity:

Oxygen Saturation = (Amount of dissolved oxygen / Dissolved oxygen capacity) * 100

Substituting the given values into the formula:
Oxygen Saturation = (6.4 / 9.5) * 100

2. Solving the equation:
Oxygen Saturation = (0.674) * 100
Oxygen Saturation = 67.4%

3. Rounding to the nearest percent:
The oxygen saturation level of the lake, to the nearest percent, is 67%.

Therefore, the correct answer is option B) 67%.

Similar ACT Doubts

In its refined form, iron is a shiny, silver-gray metal; however, when refined iron is exposed to atmospheric conditions for an extended period of time, its surface becomes flaky, pitted, and red- or orange-colored. This process is known as "rusting," and the new flaky, orange or red substance is called "rust."Below, two scientists discuss how rust forms and the composition of rust.Scientist 1:Both water and oxygen are needed for rust to form. Water is an electrolyte, meaning that it allows ions to move within it. When iron comes into contact with water, some iron naturally dissociates into iron ions (Fe2+) and free electrons. Additionally, when atmospheric oxygen (O2) dissolves in water, some oxygen reacts with water to form hydroxide ions (OH-). Because water allows ions to move freely, iron ions and hydroxide ions combine to form a new compound: iron hydroxide. However, iron hydroxide is not a stable compound. Over time, as water evaporates, it changes into a hydrated form of iron oxide. This is rust.Salts can act as catalysts for rust formation, meaning that they speed up the rate at which rust forms. However, rust can form in pure water, in the absence of added salts.Increasing the ambient temperature increases the rate of rust formation. Additionally, increasing the amount of irons surface area that is exposed to water also increases the rate at which rust forms. However, because a layer of rust is porous to water and oxygen, water and oxygen will continue to cause the interior of a piece of iron to rust even after the irons surface has been rusted.Scientist 2:Attack by acids causes rust to form. In water, acids ionize to create positively-charged hydronium (H+) ions and negatively-charged anions. Hydronium ions are electron-deficient; because of this, they attract electrons from iron. This creates iron ions (Fe2+), which are soluble in water. Once dissolved in water, iron ions react with dissolved atmospheric oxygen (O2) to create iron oxide, or rust.Acids can come from a variety of sources. For example, when carbon dioxide in the atmosphere dissolves in water, carbonic acid (H2CO3) is created. Carbonic acid is the most common cause of rusting. However, other environmental sources of acids exist. Rainwater is normally slightly acidic because it has come into contact with molecules in the atmosphere, like sulfur dioxide and nitrogen oxides. These molecules also dissolve in water to form acids. Additionally, iron itself may contain impurities such as phosphorous and sulfur, which react with water to produce acids. Both acidic environments and impurities within iron itself create the conditions under which iron rusts.Rusting can be prevented by painting the surface of iron, thus preventing it from coming into contact with water, oxygen, and acids. Iron can also be protected in a process called "galvanizing," which involves coating iron in a thin layer of zinc. Because zinc is more reactive than iron, it is corroded while the iron is protected.Q. Given that all of the following are true, which of the following, if found, provides the strongest evidence against Scientist 1s hypothesis?

Two scientists wanted to test the solubility of different substances. Solubility is a measure of how many moles of a given substance (known as the solut e) can dissolve in a given volume of another substance (known as the solvent). The solvent can also be thought of as the substance present in greater amount, while the solute can be seen as the substance present in lesser amount. The scientists performed the following experiments to investigate this property.Experiment 1The scientists tested the number of moles of several substances that could be completely dissolved in 50mL of water at various temperatures. They made their solutions by slowly adding amounts of each substance to beakers sitting on a hot plate containing water and a stirring rod until no more of the substance dissolved in the solution. The beakers were weighed before and after the additions and the difference in mass was calculated to be the added mass of the substance. The researchers then calculated the number of moles that dissolved for each trial using the molecular mass and the recorded mass for each trial. Results are recorded in Table 1.Table 1Experiment 2In this experiment, the scientists wanted to test the solubility of NaCl in a variety of liquids at several temperatures. Their procedure was similar to that of Experiment 1, but with a range of liquids and only one solid. The results are compiled in Table 2.Table 2Q.Which of the following correctly ranks the solutes from Experiment 1 in decreasing order of solubility in water at 50C?
