how much in calories is required to raise the temperature of 415 grams of chloroform from 21.4 degrees c?

Question

The specific heat of chloroform is 0.23 cal/g°c. How many joules does this equal?

Answer 1

You don't give enough information to answer the question. From 21.4 C to what higher temperature? But here is what you do.
q in cal = mass CHCl3 x specific heat CHCl3 x (Tfinal - Tinitial).

Then q in cal x 4.184 J/1 cal = ? J
