      • Since we know that 6.022*10^23 represents Avogadro's number, and is the equivalent of 1 mole, we can describe molar mass as being equal to M = m/n, where m - the gas' mass in grams; n - the number of moles of gas; We can therefore write that n = m/M, which can be used in the ideal gas law equation to get the value of the gas' molar mass PV = m/M * RT =>M = (m RT)/ (PV), so M = m * (RT)/ (PV) Here's an example of how this would look in a problem: An unknown gas has a mass of 153 g and occupies...

    How our gas density calculator works. Our gas density calculator employs this formula: \rho = MP/RT ρ = MP /RT to find the density of gas. It takes in the pressure, temperature, and molar mass of gas and calculates the density. Because R R is a constant, we do not require you to enter this value.
