Question

What is the value of the specific heat capacity of liquid water in j/mol·°c?

Answer 1

Since your units said j/mol. C, which means you are looking for molar heat capacity, then that is 75.40 j $mol^{-1} C^{-1}$

Specific heat capacity of water in  j $g^{-1} C^{-1}$ is 4.184, which has a mass unit in grams.

The molar heat capacity of water at liquid temperature is 75.40 j $mol^{-1} C^{-1}$, which takes the same units as you presented in your question.

Answer 2

he specific heat capacity of liquid water is 4.186 J/gm K.
