And the heat capacity of water is #??# #J*K^-1*g^-1#?

Explanation:

We have #"mass"#, we have #DeltaT#. We don't have no heat capacity of water.

SO I will take pity on you. The specific heat capacity of water is #4.184*J*K^-1*g^-1#. As specific heats go, this is very large.

And thus #DeltaH# #=# #"Mass "xx" Specific heat "xx""DeltaT#

#=# #22*gxx4.184*J*(""^@C)^-1*g^-1xx5""^@C# #~=500*J#

I am free to interchange #"degrees Kelvin"# and #"degrees Celsius"# because #DeltaT# is specified.
