Question

How many grams of chlorine gas are needed to make 5.20 x 100 g of a solution that is 2.00 ppm chlorine by mass?

mass:
CI,

Answer 1

mass of chlorine = 10.4 grams

Step-by-step explanation:

Mass of the solution = 5.20 × 10⁶ g

ppm chlorine by mass = 2.00

Recall that:

`ppm = (mass \ of \ chorine \ gas (solute))/( mass of the solution )* 10^6`

`2 = (mass \ of \ chorine \ gas (solute))/( 5.20* 10^6)* 10^6`

mass of chlorine = 5.20 × 2.0

mass of chlorine = 10.4 grams
