Qp in regards to Calorimeters

[victoria alvarez 3c]

In lecture yesterday, Dr. Lavelle wrote down these q_p equations :
q_p = gC△T
and
q_p = nC△T
I know the g is for grams and the n for moles (I think), but why did he substitute them in the equation? Does it change the equation somehow? Or?

Hi!

One is finding specific heat at different units of measurement. With grams, it is essentially "how much heat is required to raise 1 gram of a substance by 1 degree" whereas with moles, it is "how much heat is required to raise 1 mole of a substance by 1 degree" Hope this helps!

I think the C values are also different, ultimately the change in q will be the same regardless of if you measure in grams or moles but the Cp and Cv are different values.

Exactly as Carina said, it just depends on the particular unit or definition of C, whether it depends on mass or mol, so I suggest during problems always look at their units.
