molecular weight M a = molecular weight of air = molecular weight of C 7+ fraction M g = average molecular weight of gas mixture n = number of moles p = absolute pressure, Pa p c = critical pressure, Pa p pc = pseudocritical pressure of a gas mixture, Pa p r = reduced pressure R = gas-law constant, J/(g mol-K) T = absolute temperature, K T c ...


Under limited conditions, where gaseous mixtures conform reasonably well to the ideal-gas laws, the mole fraction can be shown to be equal to the volume fraction but not to the weight fraction. The apparent molecular weight of a gas mixture is equal to the sum of the mole fraction times the molecular weight of each component.


Equations for Gas Specific Gravity and Molecular Weight Conversion. S = M / M air, where S=gas specific gravity, M=gas molecular weight, M air =28.96443 g/mole (molecular weight of standard air - CRC, 1983). The gas specific gravity calculation does not check for unreasonable inputs. Please enter positive values.


This calculator has been scaled to use English units for temperature and pressure. Molecular weights for acetylene, air, ammonia, argon, carbon dioxide, carbon monoxide, chlorine, hydrogen, natural gas, nitrogen, oxygen, propane and steam are all provided.


COMMON GASES CONVERSION TABLE To Use This Worksheet: 1. Find the name of the compressed gas you want to convert. 2. If you know the quantity in pounds, multiply by the number in Column A 3. If you know the quantity in gallons, multiply by the number in Column B. 4. The result is the quantity of compressed gas in cubic feet. CHEMICAL


states that equal volumes (T and P the same) of gases contain the same number of molecules, no matter which gases are involved. The gas law equation works because of this property of gases. The following procedure could be used for any gas. Lower molecular weight gases would require more accurate balances to get decent results. ExpErimEnt 31.


Gas Molecular Weight. The exhaust gas molecular weight is the average molar weight of the combustion products, that is, the mass of the exhaust gas divided by the number of moles. Below is a graph of gas molecular weight versus combustion chamber pressure for liquid oxygen and kerosene at three different mixture ratios.
