from a calorimeter experiment I got this calculation:

Question

Cm=30g(4.184 J/g(Celsius))(24 Celsius-20.8Celsius)/-25g(24 Celsius-99.6 Celsius)

gives
Cm= .107 J/g(Celsius)

I have the answer here above, but when I calculate it I get different answers could someone please explain how I can get .107 J/g(Celsius) I don't understand how. Thank you!

Answer 1

My answer is 0.212

Answer 2

Thank you! Yes that's what I get too when I calculate it, but i don't know why my professor has .107 as his answer on the notes I will double check with him about it than.Thank you :)
