An industrial process of producing ammonia gas runs with a 74.0% yield. How many kilograms of ammonia gas will be produced in th
Tcecarenko [31]

Answer:

37.1 kilograms of ammonia gas will be produced in this process

Explanation:

The percentage yield of the reaction is given by:

(Yield)\%=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100

According to question

The percentage yield of the given industrial process = 74.0%

The given theoretical yield of ammonia gas = 50.1 kg

The experimental yield of ammonia gas = x

The percentage yield of the reaction is calculated a:

74.0\%=\frac{x}{50.1 kg}\times 100

Solving for x, we get:

x = 37.074 kg\approx 37.1 kg

37.1 kilograms of ammonia gas will be produced in this process
