This question asks for moles of water associated with a hydrate molecule and an experimental data is given to find out the value of moles to calculate the value on n we need to follow the following steps:

Step 01: calculate the no. of moles of water

Step 02: caltulate the no. of moles of anhydrate

step 3: then calculating the molar ratio of water to anhydrate gives the value of n
