Water equivalent of calorimeter
I am trying to solve numerical problem based on calorimetry. The water equivalent of a calorimeter is given in grams. But how is it possible as
w= mc and unit of m*c is Cal/°C.
where w= water equivalent
m= mass of the water
c= specific heat of water

Your definition of water equivalent is incorrect.
An object with a mass m, made of a substance with specific heat C, has a water equivalent w
w = m × C C w
where C w is the specific heat of water, in the same units as C
Thus, w will have the same units as m
