Finding Molar Mass with Ideal Gas Law
M = gRT/PV
Units for Molar Mass and Molecular Mass
Molar Mass: g/mol Molecular Mass: amu
Equations for Pressure and Temperature
P1/T1 = P2/T2
Equations with finding Pressure and Volume
P1/V1 = P2/V2
The ideal gas law
PV=nRT
Partial Pressure
Ptotal = P1 + P2 + P3 +......etc. When trying to find out when given percentages: (% given/ %total) x total pressure = Then add all answers together to get the pressure total
STP
Temp: 273k Pressure: 1atm Occupies 22.4L
Equations with Temperature and Volume
V1/T1 = V2/T2
Equations with Volumes and Moles
V1/n1 = V2/n2
