How much ice (in grams) would have to melt to lower the temperature of 352 ml of water from 24 degrees celsius to 6 degrees celsius ? Assume the density of water is 1.0 g/ml
Best Answer
First find how much heat is needed
352ml=352g of water
(352g)(4.18J/g c)(-18) = -26484.48 --> convert to kilojoules by dividing by 1000 = 26.48448kj

next use the heat of fusion of water (6.02kj/mol) to cancel out kilojoules

next use molar mass of water (18g/mol) to cancel out moles and you're left with g

your answer should be 79.19g
