How to Convert Molecular Weight to Density.?

Answer

1. Multiply both sides of the ideal gas equation PV = (m/M) x RT by the value M/RTV to obtain the following expression for the density: Density = m/V= PM / RT. 2. Round the molar gas constant R to the fourth digit to obtain 8.3145 J/mole x K; this

V = 0.140 L T = 90 + 273 = 363 K p = 105000 / 101325=1.04 atm n = pV / RT = 1.04 x 0.140 / 0.0821 x 363 = 0.00489 Molecular weight = 0.8965 g/ 0.00489 =183.3 g/mol d = = molar mass
