Calculate the volume of 16 grams of Sulfur Dioxide at STP

Answer 1

Sulfur dioxide (SO₂) is a gas

At STP 1 mole of any gas occupies 22.4 L

Find moles of SO₂ in 16 g and then find liters.

molar mass SO₂ = 32 + 16 + 16 = 64 g/mol

16 g x 1 mol/64 g = 0.25 moles SO₂

0.25 moles x 22.4 L/mol = 5.6 L
