Question

The specific heat capacity of silver is 0.24 J/°C ·g. (a) Calculate the energy (J) required to raise thetemperature of 150.0 g Ag from 273 Kto 295 K. (b) Calculate the energy required to raise the temperature of1.0 mol Ag by 1.0°C (called the molar heat capacity of silver(J/mol°C)
(c) It takes 1.15 kJ of energy toheat a sample of pure silver from 12.0°C to 14.9°C. Calculate the mass of the sample ofsilver (g).

The specific heat capacity of silver is 0.24 J/°C ·g. (a) Calculate the energy (J) required to raise thetemperature of 150.0 g Ag from 273 Kto 295 K. (b) Calculate the energy required to raise the temperature of1.0 mol Ag by 1.0°C (called the molar heat capacity of silver(J/mol°C)
(c) It takes 1.15 kJ of energy toheat a sample of pure silver from 12.0°C to 14.9°C. Calculate the mass of the sample ofsilver (g).

Explanation / Answer

a) Q= 150g *(0.24 J/C/g)*(295 - 273)K = 792 J b) 1 mol Ag *(107.87 g/mol) *(0.24 J/C/g)*(1 C) = 25.9 J c) Q = m*C*T m = Q/(C*T ) = (1.15 e3 J)/(0.24 J/C/g * 2.9 C) = 1652 g
