the specific heat capacity of gold is .13 J/g°C. Calculate the specific heat capacity of gold in cal/g°C. Calculate the specific heat capacity of gold in J/mol°C.

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 don't know how you do it when they only give you 2 numbers when you need at least 3 to solve.
