Calculate the amount of energy required in joules to heat 2.5 kg of water from 18.5°C to 55.0°C

I think for these you have to use the equation Q=(s)(m)(Δt). I know how to get the numbers for the letters, but i dont know how you do it when they only give you 2 numbers when you need at least 3 to solve.
