Acompound of phosphorus and chlorine contains 3.00grams of phosphorus and 10.3 grams of chlorine. how many grams of phosphorus would be in a sample of the compound containing 17.2 grams of chlorine?

mass of phosphorus = 5.01 g

Explanation:

Given data:

Mass of chlorine in sample = 10.3 g

Mass of phosphorus in sample = 3.00 g

Mass of chlorine in same sample = 17.2 g

Mass of phosphorus in this sample = ?

Solution:

To solve this problem we will use cross multiplication method.

Mass of phosphorus / mass of chlorine = Mass of phosphorus / mass of chlorine

3.00 g / 10.3 g =  x / 17.2 g

0.29126 × 17.2 g = x

x = 5.01 g

So the sample with 17.2 gram of chlorine will have 5.01 gram of phosphorus in it.
