Question

1)The metabolism of one mole of glycerol trioleate, C51 H93 O6, a common fat, produces 3.022 x 10^4 kj of heat. How many grams of the fat must be burned to raise the temperature of 50g of water from 25.0 C to 30.0 C?

2) A metal sample having a temperature of 100C and a mass of 45.2 g was placed in 50g of water with a temperature of 26C. At equilibrium, the final temperature was 32.7 C

A)How much heat flowed into the water?

B) what is the heat capacity of the metal?

3) When 2.0 g of NaOH are dissolved in 49.0 g of water, the temperature increased 10.5 C. What is the heat dissolution of NaOH expressed in joules per mole?

Explanation / Answer

a) You need to know the specific heat of water, which is 4.18 J/g
