Combined Gas Law
putting it all together!
-
Combined Gas Law
P1V1 = P2V2T1T2for a fixed amount (# moles) of gas
-
Combined Gas Lawgiven 5 of 6 variables, can identify 6th
if a variable is constant, just ignore it
P1V1 = P2V2 T1 T2
-
Avogadros Hypothesisequal volumes of gases at same T and P contain equal # of particles
6.02 x 1023 particles
-
Molar Volumereminder:
1 mole of any gas at STP occupies 22.4 L/mol
-
3 containers same size, same T, same P, 1mole gasBox A HeBox BN2Box C CH4What can you say about # of molecules in each box? # molecules is the same in each box (1 mole each substance)What can you say about # of atoms in each box?B = 2 x A ; C = 5 x A
