Answer to Question #181716 in General Chemistry for Sally

Question

If 13.4 kj of energy is added to 1.0 kg of ice at 0°c how much water is produced? How much ice is left?

Answer 1

So... 6.01 kJ of energy can melt 1 mole of ice

Then... 13.4 kJ ---> x (How many moles of ice are melted by 13.4 kJ of energy?)

$x = \frac{13.4}{6.01}=2.23 moles$

2.23 mols ice are melted?

Grams = mols x molar mass = approx 40 g. How much ice did you have? That's 1,000 g. How much ice is left. Approx 1000-40 = 960g
