Question

Quizplus · Accepted Answer

The molar mass of CO is 28.01 g/mol. For 10.0 g of CO, moles = 10.0 g / 28.01 g/mol = 0.357 moles. The reaction releases 482 kJ for 2 moles of CO, so for 0.357 moles, the heat released is (482 kJ / 2) * 0.357 = 86.0 kJ.

The Value of ΔH° for the Reaction Below Is -482
