Molar mass: 32.042 g ... with the chemical formula C H 3 OH ... systems is the basis of several technologies related to gas to liquids. These include methanol-to ...
Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures: log 10 (P) = −(0.05223)a/T + b, where P is in mmHg, T is in kelvins, a = 38324, and b = 8.8017.
How much gas is present could be specified by giving the mass instead of the chemical amount of gas. Therefore, an alternative form of the ideal gas law may be useful. The chemical amount, n (in moles), is equal to total mass of the gas (m) (in kilograms) divided by the molar mass, M (in kilograms per mole): =.
An ideal gas is a theoretical gas composed of many ... The speed of sound in an ideal gas is given by the Newton-Laplace formula: ... M is the molar mass of the gas.
The ideal gas law can be re-arranged to obtain a relation between the density and the molar mass of an ideal gas: = and = and thus: = where: P = absolute gas pressure; V = gas volume; n = amount (measured in moles) R = universal ideal gas law constant; T = absolute gas temperature; ρ = gas density at T and P; m = mass of gas
The gas constant occurs in the ideal gas law: = = where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. R specific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.

The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
