How much heat energy is required to heat up 50.0 grams of water from 20.2 degrees Celsius to 34.2 degrees Celsius? I want o use the Q=mc(change in temp) formula but I am only given the m and difference in temp in this question so I am not sure of what I am supposed to do.

Hi. Well, what is the specific heat capacity of water? use that number to plug into Q=M(c)(delta T) with the rest of your information.
In this problem its given in grams, so you use 4.19 J/g C
