At a given temperature, the vapor pressure of pure acetone (CH3COCH3, 58.00 g/mol) is 337 torr. At the same temperature, the vapor pressure of pure chloroform (CHCl3, 119.35 g/mol) is 225 torr. Consider a solution containing 21 g of acetone and 62.3 g of chloroform. Calculate the total vapor pressure above the solution (in torr to 0 decimal places).
