Answer:
The value of n in the hydrate formula is 5 ,
.
Explanation:
![CuSO_4.nH_2O\rightarrow CuSO_4+nH_2O](https://tex.z-dn.net/?f=CuSO_4.nH_2O%5Crightarrow%20CuSO_4%2BnH_2O)
Mass of hydrate of copper sulfate = 14.220 g
Moles of hydrate of copper sulfate =![\frac{14.220 g}{(159.5+n\times 18) g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7B14.220%20g%7D%7B%28159.5%2Bn%5Ctimes%2018%29%20g%2Fmol%7D)
Mass of copper sulfate after heating = 8.9935 g
Moles of copper sulfate = ![\frac{8.9935 g}{159.5 g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7B8.9935%20g%7D%7B159.5%20g%2Fmol%7D)
![\frac{14.220 g}{(159.5+n\times 18) g/mol}=\frac{8.9935 g}{159.5 g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7B14.220%20g%7D%7B%28159.5%2Bn%5Ctimes%2018%29%20g%2Fmol%7D%3D%5Cfrac%7B8.9935%20g%7D%7B159.5%20g%2Fmol%7D)
Solving for n, we get:
n = 5
The value of n in the hydrate formula is 5 ,
