When 0.1625 g of magnesium is burned in a bomb calorimeter that has a heat capacity of 3.03 kj/ ∘
c, the temperature increases by 1.252 ∘
c. how much heat (kj/mol) is liberated during the burning of the magnesium?

Heat released during the burning of 0.1625 g of magnesium is 3.79356 kilo Joules.

Explanation:

Mass of the magnesium : 0.1625 g

Heat capacity of the bomb calorie-meter,C = 3.03 kJ/°C

Change or increase in temperature = 1.252°C

Heat =

Heat released during the burning of 0.1625 g of magnesium is 3.79356 kilo Joules.

the answer is d. 74.02
