Question

ΔH = -174 kcal/mol (-728 kJ/mol ) methanol for the process. How many kilocalories are released by burning 2.00 mol of methanol?

Answer 1

2.00 mol of methanol releases 348 kcal of energy when combusted.

Step-by-step explanation:

The given value of ΔH is -174 kcal/mol (-728 kJ/mol) for the combustion of methanol.

This means that for every 1 mole of methanol combusted, 174 kcal of energy are released.

To find the amount of energy released by burning 2.00 mol of methanol, we can use dimensional analysis:

2.00 mol methanol x (-174 kcal / 1 mol) = -348 kcal
