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?

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
