Gases & Stoichiometry

Molar Volume

1 mol of gas = 22.4 L molar volume

What volume would be occupied by 0.77 moles of helium gas at STP?

Density of Gases

Density = molar mass/molar volume

What is the density of (in grams per liter) of carbon dioxide gas at STP?

Using mole-mole Conversions

Use a balanced equation to acquire mole/volume ratios when determining the amount of a gas in a chemical reaction.

Using mole-mole Conversions

How many liters of carbon dioxide gas are produced by the complete combustion of 95.0 L of propane gas, C3H8? C3H8 + 5O2 3CO2 + 4H2O

Using mole-mole Conversions

What volume of carbon dioxide gas (at STP) can be collected from the complete combustion of 400 g of octane gas, C8H18?

2C8H18 + 25O2 16CO2 + 18H2O
