A common antifreeze for car radiators is ethylene glycol, CH2(OH)CH2(OH). How many milliliters of this substance would you add to 4.2 L of water in the radiator if the coldest day in winter is −25°C? (The density and boiling point of ethylene glycol are 1.11 g·cm−3 and 470. K, respectively. Assume the density of water at its freezing point is 0.99987 g·cm−3, and Kf for water is 1.86 K·kg·mol−1.)

A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.
