Natural gas, or methane, is an important fuel. combustion of one mole of methane releases 802.3 kilojoules of energy. how much energy does that represent in kilocalories?

191.7497 Kilocalories

Explanation:

Step 1:

Data obtained from the question:

Energy released = 802.3KJ

Step 2:

Conversion of the energy released in kilojoules to kilocalories. This is illustrated below:

1 KJ = 0.239 kilocalorie

Therefore, 802.3 KJ = 802.3 x 0.239 = 191.7497 Kilocalories

From the calculation above, 802.3 KJ is equivalent to 191.7497 Kilocalories

the answer would be c
