In the laboratory, a student performed an experiment in which the final length of a piece of wire was a significant measurement. In three separate experiments, the student found the length of wire after the experiment to be 23.50 mm, 25.0 mm, and 35 mm. Find the average of the three trials, to the correct number of significant figures, and decide if these measurements gave an accurate result.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

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 = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
