Perspiration has a slight acidity because of the presence oflactic acid (C3H6O3). Suppose weanalyze the perspiration of a chemistry student running late toclass. If the density of the perspiration were 1.23 g/mL and the mass percent lactic acid were foundto be 4.82%, what would you calculate asthe mole fraction, molarity, and molality of the lactic acid?(Assume that the perspiration contains only lactic acid andwater.)
