Calculate the mole fraction of ethylene glycol (C2H6O2) in a solution
containing 20% of C2H6O2 by mass Assume that we have 100 g of solution (one can start with any amount of
solution because the results obtained will be the same) Solution will
contain 20 g of ethylene glycol and 80 g of water Molar mass of C2H6O2 = 12 × 2 + 1 × 6 + 16 × 2 = 62 g mol–1
