Question

Carlos is making phosphorous trichloride using the equation below. He adds 15 g of phosphorus.

2P +3Cl2 → 2PCl3

How much chlorine would be found in the product?

5 g
7.5 g
45 g
90 g

Answer 1

c

Step-by-step explanation:

Answer 2

Given:

The balanced chemical reaction of the synthesis of phosphorus trichloride:

2P + 3Cl2 ===> 2PCl3

Initial amount of phosphorus = 15 grams

The amount of product produced from 15 grams of phosphorus:

15 grams / 31 g/mol * (2/2) = 66.46 grams PCl3

The amount of chlorine is 44.31 grams, nearest to 45 grams.
