Given :
Energy , E = 330 J .
Initial temperature ,
.
Final temperature ,
.
Mass of benzene , m = 24.6 g .
To Find :
The molar hear capacity of benzene at constant pressure .
Solution :
Molecular mass of benzene , M = 78 g/mol .
Number of moles of benzene :
![n=\dfrac{24.6}{78} \ mol\\\\n=0.32 \ mol](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B24.6%7D%7B78%7D%20%5C%20mol%5C%5C%5C%5Cn%3D0.32%20%5C%20mol)
Energy required is given by :
![q=nC_p\Delta T\\\\330=0.32\times C_p\times (28.7-21)\\\\C_p=\dfrac{330}{0.32\times 7.7}\ J\ mol^{-1}^oC^{-1} \\\\C_p=133.9\ J\ mol^{-1}^oC^{-1}](https://tex.z-dn.net/?f=q%3DnC_p%5CDelta%20T%5C%5C%5C%5C330%3D0.32%5Ctimes%20C_p%5Ctimes%20%2828.7-21%29%5C%5C%5C%5CC_p%3D%5Cdfrac%7B330%7D%7B0.32%5Ctimes%207.7%7D%5C%20J%5C%20mol%5E%7B-1%7D%5EoC%5E%7B-1%7D%20%5C%5C%5C%5CC_p%3D133.9%5C%20J%5C%20mol%5E%7B-1%7D%5EoC%5E%7B-1%7D)
Hence , this is the required solution .
