III. Ideal Gas Law

- Ch. 11 - Gases

A. Avogadros Principle

- Equal volumes of gases contain equal numbers of

moles - at constant temp pressure
- true for any gas

A. Ideal Gas Law

Merge the Combined Gas Law with Avogadros

Principle

IV. Gas Stoichiometry at Non-STP Conditions(p.

- Ch. 10 11 - Gases

A. Gas Stoichiometry

- Moles Liters of a Gas
- STP - use 22.4 L/mol
- Non-STP - use ideal gas law
- Non-STP
- Given liters of gas
- start with ideal gas law
- Looking for liters of gas
- start with stoichiometry conv.

B. Gas Stoichiometry Problem

- What volume of CO2 forms from 5.25 g of CaCO3

at 103 kPa 25ºC

CaCO3 CaO CO2

5.25 g

Lnon-STP

Looking for liters Start with stoich and

calculate moles of CO2.

1 mol CaCO3 100.09g CaCO3

5.25 g CaCO3

1 mol CO2 1 mol CaCO3

1.26 mol CO2

Plug this into the Ideal Gas Law to find liters.
