2011 Final Question 1A

Postby Hannah Markovic 3C » Sat Mar 12, 2016 11:51 pm

"Suppose you want to use methane gas (deltaH = -890 kJ/mol) to boil 50.0 mL of water at 25.0 degrees C. How many grams of methane gas would need to be combusted to generate the required heat?"

The answer for this question only calculates the amount of heat to raise the water to 100 degrees (15.7 kJ) and doesn't calculate the amount of heat to boil the water. Am I missing something or is the printed solution wrong?

The printed solution is wrong. You should also boil it.
