According to boiling point elevation equation: Δ T = i Kb m when ΔT (change in boiling point) = 7.10 C° and i (van't Hoff factor)= 1 and Kb = 0.520 so, by substitution: 7.10 = 1*0.520 *m m = 7.1 / 0.52 = 13.65 m
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds.
