How much heat is required to vaporize 25 grams of water at 100 degrees C. Hvaporitation=2.3 kj/g

[From: ] [author: ] [Date: 12-04-27] [Hit: ]
It is necessary to know that this happens at 100 degrees, but that fact doesnt enter into the calculation.......
So would it be (2.3 kj/g) (25g)? What do I do with the 100 degrees celcius? Is it just extra information that is not needed?

You are correct. It is necessary to know that this happens at 100 degrees, but that fact doesn't enter into the calculation.
