WebQ] A Solution contains 30% by mass in carbon tet. Calculate the mole fraction of benzene using Mole Fraction Formula. Solution: Total mass of the answer = 100 g. Mass of benzene = 30 g. Therefore, mass of carbon tet = (100 – 30)g. Benzene’s molar mass (C6H6) = (6 × 12 + 6 × 1) g mol – 1 = 78 g mol – 1. Hence, C6H6’s number of moles ... WebMolecular Models C.
