Chemistry Help Please

Help with #8?

Q = M x DELTA T x Cp

1.86 x 10^3 mL = cc = g of H2O

That's M, Delta T is 63.2C (86.7 - 23.5)

But how do I find Cp, which has to be in calories / grams x celcius

isn't CP a constant and it varies by substance?

yeah, and since it's water it should be 1 cal/g*degree C

or is it in different units?

Sorry all my chemistry reference and PChem books are at work. Do a search on Google or Yahoo.

Heat Capacity? or is that specific heat at constant pressure?

For specific heat at constant pressure go here

I think it's specific heat...I did this stuff freshman year in highschool. Loved chemistry but it's been awhile heh.
