Question

The molar heat capacity of silver is 25.35 J/mol*C. How much energy would it take to raise the temperature of 10.2 g of silver by 14.0 degrees C?

Answer 1

You have to use  

q

=

m

C

Δ

T

m

=

10.2

g

 

C

=

25.35

(J/mol)*C

T

=

14

C

First convert  

10.2

to moles by dividing it by the molar mass of silver  

10.2

107.8682

=

.0945598425

Than plug into equation

q

=

(

.0945598425

m

o

l

)

(

25.35

)

(

14

)

q

=

33.6

J
