问题描述：
The specific heat capacity of silver is 0.24 J/°C·g.
(a) Calculate the energy required to raise the temperature of 180.0 g Ag from 273 K to 303 K.
_____________J
(b) Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0°C (called the molar heat capacity of silver).
_____________J/mol°C
(c) It takes 1.05 kJ of energy to heat a sample of pure silver from 12.0°C to 14.7°C.Calculate the mass of the sample of silver.
_____________g
答
(a)180.0*(303-273)*0.24=1296J
(b)1.0 mol Ag是108g,所以 108*1*0.24=25.92J
(c)1.05*1000/(14.7-12.0)再/0.24=162.04g
