Calculation of Concentration of Solution

To calculate the concentration of the solution, we need to determine the amount of alcohol present in the mixture and express it as a ratio to the total volume of the solution. The concentration of a solution is commonly expressed as the amount of solute (in this case, alcohol) per unit volume of the solution.

Step 1: Determine the amount of alcohol in the solution

The solution contains 5.6ml of alcohol mixed with 75ml of water. Therefore, the amount of alcohol in the solution is 5.6ml.

Step 2: Calculate the total volume of the solution

The total volume of the solution is the sum of the volume of alcohol and the volume of water. In this case, it is 5.6ml + 75ml = 80.6ml.

Step 3: Calculate the concentration

The concentration of the solution can be calculated by dividing the amount of alcohol by the total volume of the solution and multiplying by 100 to express it as a percentage.

Concentration of alcohol = (Amount of alcohol / Total volume of solution) * 100

Substituting the values, we get:

Concentration of alcohol = (5.6ml / 80.6ml) * 100 = 6.94%

Therefore, the concentration of the solution is 6.94%.

Explanation:

The concentration of a solution is a measure of the amount of solute (alcohol in this case) dissolved in a given amount of solvent (water in this case). In the given problem, the solution contains 5.6ml of alcohol mixed with 75ml of water, making a total volume of 80.6ml. To calculate the concentration, we divide the amount of alcohol by the total volume of the solution and multiply by 100 to express it as a percentage.

The concentration of this solution is found to be 6.94%. This means that for every 100ml of the solution, 6.94ml is alcohol. It is important to note that the concentration of a solution can be expressed in various units, such as molarity, molality, or percentage. In this case, we have expressed it as a percentage.

By calculating the concentration, we can determine the relative amount of alcohol present in the solution, which is useful for various applications such as in chemistry, medicine, and industry.
