69.7 kJ of heat is applied to a 1017-g block of metal, the temperature of the metal increases by 11.4 °C.?

Question

Calculate the specific heat capacity of the metal in J/g °C.

Answer 1

This is a very simple problem if you just look at the units of what you are given and what you want to solve for.

You want to end up with joules /g-C

So take the values that you have and either multiply or divide depending on where the unit is supposed to be in your final answer. But first you need to convert any numbers to the right units, if necessary.

69.7 kJ x 1000J/kJ = 69700J

69700J / 1017g / 11.4C = 6.01 J/g-C

Answer 2

You are given the units for specific heat (J/g °C)

All you need to do is use the numbers you have to get the unit you want.

69.7 kJ = 69700 J
1017 g
11.4°C

69700 J / (1017g * 11.4 °C) = 6.01 J/g °C
