The level of contamination of chloroform was found to be 15 ppm. It means 15 g of chloroform is present in how many grams of solution?a)1000 gb)106 gc)100 gd)1.0 gCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

The answer is b)10^6 Bcoz, ppm=parts of solute/parts of solution×10^6 Here,it is given ppm of CHCl3=15 mass of solute= 15g mass of solution is=x .•. 15=15/x × 10^6 .•.x=10^6 Hope u get it...😄😄😄

Answer

1 ppm is equivalent to 1 part out of 1 million (106) parts.

∴ Mass percent of 15 ppm chloroform in water

Answer

Ppm means 1 gram present in 1 million molecules of the solvent...

Answer

Ppm generally means parts per million that is in respect to your mentioned question 15 gm chloroform was present in a million grams

Answer

Given information:
The level of contamination of chloroform is 15 ppm.

To find:
The number of grams of solution that contains 15 g of chloroform.

Solution:
To solve this problem, we need to understand what ppm means and how it can be used to calculate the amount of chloroform in the solution.

Parts per million (ppm):
PPM is a unit used to represent the concentration of a substance in a solution or mixture. It is defined as the number of parts of a substance per million parts of the entire solution. In this case, the concentration of chloroform is given as 15 ppm.

Conversion:
To convert ppm to grams of chloroform in a solution, we need to know the total weight of the solution. Let's assume the weight of the solution is 'x' grams.

Calculation:
Since the concentration of chloroform is given in ppm, we can calculate the weight of chloroform in the solution using the following formula:

Weight of chloroform = (ppm/10^6) * weight of solution

Substituting the given values:

Weight of chloroform = (15/10^6) * x
Weight of chloroform = 15x/10^6

We are given that the weight of chloroform is 15 grams. So we can equate the two values:

15 = 15x/10^6

Cross multiplying, we get:

15 * 10^6 = 15x
x = (15 * 10^6)/15
x = 10^6

Therefore, the weight of the solution is 10^6 grams.

Answer:
The weight of the solution containing 15 g of chloroform is 10^6 grams, which is equivalent to option B.
