Question

What volume of stock solution and water must you add to prepare 36.25ml of a 1.25M solution

Answer 1

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 :

`M=(n)/(V)`

So ,
`V=(n)/(M)`

Here , n is number of moles and M is molarity .

Putting all values in above equation , we get :

`V=(36.25)/(1.25)\\\\V=29\ L`

Therefore , volume of water required is 29 L .
