Answer to Question #181278 in General Chemistry for Mel

Question

What is the theoretical yield, in grams, of SO₃(𝑔) that can be produced from 25.0 grams of SO₂(𝑔) according to the reaction below?

2SO2(g)+O2(g)—>2SO3(g)

Answer 1

Molar mass of SO2=64g

Molar mass of SO3=80g

From the balanced equation

2mol of SO2 gives 2mol of SO3

1mol of SO2 gives 1mol of SO3

64g of SO2 gives 80g of SO3

25.0g of SO2 will give 80/64 x 25.0= 31.25g

Theoretical yield of SO3= 31.25g
