Question

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?

Answer 1

191.7497 Kilocalories

Step-by-step 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

Answer 2

Answer: 802.3 kilo Joules of energy represents 191.75 kilo Calorie of energy.

Step-by-step explanation:

Energy released during combustion of one mole methane = 802.3 kilo Joules

If 1 kilo Joule = 0.239006 kilo Calorie

Then ,802.3 kilo joule will be = 802.3
`*`0.239006 kilo Calorie

802.3 kilo joule = 191.75 kilo Calorie

Hence, the energy in kilo Calorie is 191.75 kilo Calorie.
