Hi, one of my homework problems i recieved was "A water heater can generate 32, 000kJ/h. How much water can it heat from 15 C to 50 C per hour?" I am having trouble figuring out what formula I would use?

Let's see, you have the amount of heat, Q=32,000,000 J
you have a change in temperature, $$\Delta T$$=35 degrees
you have water with a specific heat, c = (look it up)
and you need mass m=?

You can't find the right formula? You should look again.
