It is 4/10 of moles is this ane halp?
Answer:

Explanation:
Given that,
Mass of the sample, m = 275 g
It required 10.75 kJ of heat to change its temperature from 21.2 °C to its melting temperature, 327.5 °C.
We need to find the specific heat of the metal. The heat required by a metal sample is given by :

c is specific heat of the metal

So, the specific heat of metal is
.
