Mass divided by Molar Mass (m/MM)

How do you find the temperature in Kelvin from degrees Celsius
○C+273.15=○K

What is the mercury unit of pressure?
Meter of Mercury (mm Hg)

What is a bar equal to in pascals?
10^{5}Pa

What does atm stand for?
atmosphere

What is Standard Pressure and Temperature?
0^{○}C and 1atm

What is the equation for the Ideal Gas Law?
PV=nRT

What is the volume of a mole of any gas at STP?
22.4L

What is the value of "R" in Ideal Gas Law?
0.0821

What is the unit for "R" in Ideal Gas Law?
(L*atm)/(mol*K)

What is the equation for finding density of a gas?
(m/V)=MM(P/RT)

What are the full conversion factors of pressure?
1.013bar =1atm = 760 torr = 760mm Hg = 14.7psi = 10^{5} Pa

What is the equation for finding the height of mercuric pressure for a substance with a differing density than the original?
D_{a}h_{a}=D_{b}h_{b}

What is the equation for total pressure exerted when two species coexist?
 P_{tot }= [(n_{a}+n_{b}) RT]/V
 or
 P_{tot }= P_{a} + P_{b}

How do you calculate partial pressure when total pressure and composition of mixture are known?
P_{a }= (n_{a}/n_{tot})*P_{tot}
