The specifi heat of a certain

Question

The specific heat of a certain type of cooking oil is 1.75J /(g-^ C). How much heat energy is needed to raise the temperature of 2.48 kg of this oil from 23 deg * C 191 °C?

I tried and got 729.12, so please hep

q =

Answer 1

Note that the mass of oil is in kg so m =2.48 kg = 2480g

Temperature change is 191-23 = 168 º^C

So Q=mcΔT =2480(1.75J/g.º^C)(168º^C)=729120J which you can round to 3 significant figures so your answer would be 729000J.

Always check the units.
