Use this simple equation for dilution problems like this.
MiVi = MfVf
where the subscripts are initial and final and V is volume and M is molarity, or Normality in this case.
So: (1N)(Vi) = (0.1N)(20 ml)
Solve for Vi and you get 2 mL.
Now add the 2 mL to a 20 mL volumetric flask that contains 10 mL of water. ALWAYS add acid to water, NEVER water to acid. Mix and add water until the volume reaches the 20 mL mark. You now have 20 mL of a 0.1N HCl solution.

We’re missing 1 factor here, which volume do you like to make ( or theoretically we can start also from how much volume of the 1N solution do you have.
But generally one normally start from a wanted volume of a wanted concentration.
so lets assume you need 1 liter of 0.1 N
The formula :
V1 x N1 = V2 x N2
we know all except V1, so :
V1 = V2 x N2 / N2
V1 = 1000 ml x 0.1 N / 1N =
100 ml
So take with a pipette 100 ml of the 1N solution and drop it in a 1000 ml volumetric flask, add water to the 1000 ml mark, shake it, done, there is your 1 liter 0.1 N solution.

Measure the volume of the hcl you have and use the formula to add water and decrease tge concentration.
V1N1=V2N2
If you have 1 litre 1N HCl,
1*1=V2*0.1
i.e. V2 = 10 litres

1 N = 1 M
1 X = number of mol
0.1 = 1 x 1 / (1 + X)
X = 9 L
Take 1 L of the 1 M solution and mix it carefully with 9 L of water
final solution = 1 mol / 10 L = 0.1 M
1 N = 1 M
1 X = number of mol
0.1 = 1 x 1 / (1 + X)
X = 9 L
Take 1 L of the 1 M solution and mix it carefully with 9 L of water
final solution = 1 mol / 10 L = 0.1 M

First of all check the specific gravity(sg) on HCL reagent bottle and percentage of concentration
Use the formula for stock calculation
N=sg*%*1000/(equivalent wts*100)
By this to find out stock normality of HCl solution
Now use
M1V1(stock)=M2V2(required) means
Required means 0.1N in 100mL
M2=0.1 and V2=100
M1= find from above formula i.e N=sg*%*1000/(equivalent wts*100)
Now you find V1 from M1V1=M2V2
Clear
Hope you will get it
