Determine molar mass of gas
WebFeb 10, 2015 · d = m V. Rearranging the ideal gas equation to isolate V and substituting into the density equation yields. d = m P n R T = ( m n) P R T. The ratio m / n is the definition of molar mass, ℳ: ℳ = m n. The density equation can then be written. d = ℳ P R T. WebThis online calculator converts grams to liters and liters to grams given a gas formula. It uses molar volume of a gas at STP (standard temperature and pressure) This calculator finishes the topic started in Convert moles to liters and liters to moles calculator. Because the molar volume is the same for all ideal gases and is known, we can ...
