What volume of stock solution and water must you add to prepare 36.25ml of a 1.25M solution
Serjik [45]

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=\dfrac{n}{V}

So , V=\dfrac{n}{M}

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

Putting all values in above equation , we get :

V=\dfrac{36.25}{1.25}\\\\V=29\ L

Therefore , volume of water required is 29 L .

How does the tendency of iron to rust depend on ph?
mojhsa [17]
The  tendency  of  iron  to  rust   depend  on  the  Ph   of solution

 The   formation  of  rust  increases  as  the  PH  decreases.  This  led  agent  of  rusting  that  is  oxygen  gets  more  positive  as  H+  ions  increase   which  facilitate     rusting. The    lower  the  Ph  level  the   quick  the   corrosion.
