The heat change that accompanies the formation of 1.00 mol of carbon dioxide from its elements is −393.7 kJ/mol. What heat change accompanies the formation of 0.631 mol CO2?

-248.425 kJ/mol

Explanation:

This question can be done by simply taking the ratios:

Since the given the heat change for 1.00 mol of is -373.7 KJ/mol. Let us consider the required Heat Exchange at 0.631 mol of

We can write:

KJ/mol

h let me think

first one is the correct answer
