Title: thermochem
Post by: hitleap on November 28, 2012, 03:20:12 PM
Hello, I have a few questions:
1)
The specific heat of aluminum is 0.903j/g*C
What is the molar heat of capacity of aluminum?
I think it is 24.4 J/mol*C
is that correct?

2) The molar heat of capacity of ammonia gas is:
a) about the same as that of helium gas
b) one half of that of helium gas
c) exactly the same as that of helium gas
d) less than that of helium gas
e) greater than that of helium gas
I think it is E, because the molar mass is greater.

Yes & yes.
