How can we convert 25 percent of ammonia solution to 10 M?

25% ammonia solution means 25g Ammonia in 100ml of water. To convert it into moles i.e for 1000ml solvent,

25x100=250

which means 250g of ammonia is present in 1000ml of water to make a 25%solution. To convert it into molar solution we will divide 250 by the molecular mass of ammonia i.e 17.

250/17= 14.71M

This means that 25% ammonia solution contains 14.71 moles of ammonia.

Now we will use the formula

M1V1=M2V2

Let's say we want to make 10 molar solution in 500ml water. Then,

M1=14.71

V1=?

M2=10

V2=500

Putting values in the above equation:

14.71xV1 = 10x500

V1 = 10x500 / 14.71 = 340ml

We will take 340ml of the 25% ammonia solution and make the volume up to 500ml with water. This will be our 10 molar solution of Ammonia.
