DESCRIPTION
140. Solving a chemistry problem
Calculate the surface tension of an aqueous solution of butanol (C4H9OH) with a concentration of 0.1 mol / dm3 at 20 C, if the surface tension of a propanol solution (C3H7OH) of the same concentration at the same temperature is 65.5 * 10-3 n / m. The Traube coefficient is 3. The surface tension of water at this temperature is 72.5 * 10-3 n / m
