Question

What is the heat capacity of 190g of liquid water? I came up with 794.96 but it says my sig figs are wrong? Help?????

Answer 1

In multiplication and division, you may not have more places than in the least precise value used in the process. You ave 3 s.f. in 190; therefore, you are allowed only 3 in the answer. Therefore, it should be rounded to 795 although I don't know how you came up with that number AND you have no units.

Answer 2

I used:

specific heat of 4.184 x 190g which = 794.96

Is that not the correct heat capacity?
