The specific heat capacity of silver is 0.24 J/°C·g.
(a) Calculate the energy required to raise the temperature of 140.0 g Ag from 273 K to 295 K.
(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).
q = mass Ag x specific heat Ag x (Tf - Ti)
You have mass Ag, sp. H. Ag, and Tf (final T) and Ti (initial T). Solve for q.
You have specific heat Ag which is the energy required to raise 1 g Ag by 1 degree C.
0.24 J/g*c x (107.87 g Ag/mol) = ??
to find C am i just using the equation from a?
You didn't post a c part.
I will be happy to critique your work.
a. energy= mass*c*deltaTemp
b. energy/mole= energy/gram*grams/mole
i don't understand b.
You have specific heat in J/g. So you multiply the molar mass to obtain J/mol.
