I'm not quite sure what units you were provided for the enthalpy of vaporization of water, but dependent upon the units, it may make this a little bit easier or a little bit more challenging.

If we have 20 grams of ice, sorry, of water at 100 degrees celsius, to vaporize it, the delta h of vaporization value that i have is in units of joules per gram, 2 ,260 joules per gram.
00:37
We can then convert the jewels to calories, knowing there are 4 .184 joules in one calorie.
00:45
We then do a similar calculation with the second mass 8 .00 grams.
00:55
We convert those grams into joules, 2 ,260 joules in one gram.

And then from jules to calories.

One calorie, 4 .184 jules...
