Asked by Selena
Please help me with this question:
Calculate the theoretical yield amount of CaCl2 that would be required to change the temp of 50ml of water from room temp 20degree to 45 degrees. Heat Capacity H20 is 4.184 Jg^-1deg^-1 and density is 1g/mL.
I've already calculated: Q=mc delta T
(50g)(4.184J/g^-1)(45-20deg)
=5230 J
so then the Q of CaCl2 is -5230 J. What do I do from here I am so confused!
Please help
