Question
Calculate the quantity of heat gained or lost:
a) 3.50 mol H2O freezes at 0.0 oC
b) 0.44 mol of steam condenses at 100 oC
a) 3.50 mol H2O freezes at 0.0 oC
b) 0.44 mol of steam condenses at 100 oC
Answers
a.
3.50 x molar mass = grams H2O.
q = grams H2O x heat fusion.
b.
0.44 moles H2O x molar mass = ?? grams steam.
q = mass steam x heat vaporization.
3.50 x molar mass = grams H2O.
q = grams H2O x heat fusion.
b.
0.44 moles H2O x molar mass = ?? grams steam.
q = mass steam x heat vaporization.
