Question | Answer |
Mass (in grams) of gas | w=nM or w=dV |
Variations of Ideal Gas Law | PV=(w/M)RT or PV=(d/M)RT |
SI version of Gas Constant R (Pa*m3 -> J/molK) | 8.3145 |
When collecting a gas over a liquid | P[gas]=P[total] - P[liquid] |
STP version of Gas Constant R (L*atm/molK) | 0.0821 |
Ideal Gas Law | PV=nRT |
Standard Molar Volume | 22.414 L |
Avogadro's Hypothesis | equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules |
Avogadro's Number | 6.02E23 |
Density Equation | D=m/V |
Charle's Law | constant pressure |
Density varies inversely to volume | D1V1=D2V2 |
Boyle's Law | constant temperature |
Standard Pressure | 1 atm 101,325 Pa 760 torr about 1 bar |
Pressure in Pascals | P[Pa]= force[N]/area[m2] |
Pressure exerted by a column of fluid | P=height*density*9.81 |
Dalton's law of Partial Pressures | the sum of the pressures of the gases in a mixture is the total pressure exerted |
Changes in density with temperature and pressure | D2=D1V1/V2 or D2=(P2/P1)(T1/T2) |
Guy-Lussac's Law | constant volume |
