Question

Calculate the molar mass of a volatile liquid of mass 1.100 g which contains 0.0025 mol

Answer 1

Answer:

number of moles = n = pV/RT . But we go one step further, because we will also measure the mass of the evaporated liquid. Knowing the mass and the number of moles will allow us to compute the molar mass of the liquid: molar mass = (mass)/(number of moles).
