where
Q is the amount of energy supplied to the substance
m is the mass of the substance
is its specific heat capacity
is the change in temperature
In this problem, we have:
Q = 2500 J of energy supplied to the water
is the specific heat capacity of water
is the change in temperature of the water
Therefore we can solve for m to find the mass of the water:
