Calculate the volume of gas that is formed by the interaction of 50.4 g of sodium sulfite with nitric acid.

Given:
m (Na2SO3) = 50.4 g
To find:
V (SO2)
Decision:
Na2SO3 + 2HNO3 = 2NaNO3 + H2O + SO2
n (Na2SO3) = m / M = 50.4 g / 126 g / mol = 0.4 mol
n (Na2SO3): n (SO2) = 1: 1
n (SO2) = 0.4 mol
V (SO2) = n * Vm = 0.4 mol * 22.4 L / mol = 8.96 L
Answer: 8.96 L
