The freezing point of camphor is 178.4 degree C and its molar freezing point depression constant (K_1) is 37.7 degree C-kg/mol. How many grams of naphthalene (C_10H_8; molar mass - 128.17 g/mol; a solute, not the solvent, in this question) should be mixed with 12.0 g of camphor to lower the freezing point to 170.0 degree C?
