Law of Partial _____

Given that there are i gas components completely mixed and occupying a volume V at temperature T.

Pressure

p = \sum_i p_i

given that the volume p and all p_i are acting in are equal.

Internal Energy

U = \sum_i U_i

Volumes

V = \sum_i V_i

given that the pressures of V and all values of V_i are equal.

This is useful as V \propto n meaning that we can use volumes to achieve stoichiometric (ideal) mixtures of gases for combustion reactions.

Avogadro's Number and the Mole

Avogadro's Number is roughly 6.022\times10^{23}. The mass in grams of this many particles of an element is pretty much equal to:

• its atomic mass number
• the number of nucleons in the nucleus
