Given :
Number of moles , n = 36.25 mol .
Molarity , M = 1.25 M .
To Find :
The volume of water required .
Solution :
Moarity is given by :
[tex]M=\dfrac{n}{V}[/tex]
So , [tex]V=\dfrac{n}{M}[/tex]
Here , n is number of moles and M is molarity .
Putting all values in above equation , we get :
[tex]V=\dfrac{36.25}{1.25}\\\\V=29\ L[/tex]
Therefore , volume of water required is 29 L .
