Question

Calculate the volume at stp occupied by 14 gram of nitrogen

Answer 1

Find the number of moles of nitrogen by dividing its mass by molar mass:

14 gram ÷ 14 g/mol = 1 mole

Calculate the volume at STP by multiplying the number of moles with molar volume (22.4 dm³/mol):

1 mole × 22.4 dm³/mol = 22.4 dm³
