Homework Help: Chemistry

Posted by Sarah on Wednesday, May 19, 2010 at 10:42pm.

How many kilojoules of heat are absorbed when 1.00L of water is heated from 18 degrees C to 85 degrees C?

Did I do this right?

1000g H2O x 4.18 x 67 = 280060 kilojoules

(my book says the specific heat for water in J/g x degrees C = 4.18, and for cal/g x degrees C = 1.00) Would i multiply 1000g x 67 x by 4.18 or 1?
