Answer:
0.4M
Explanation:
This is known as Dilution.
Even when we dilute a substance in a solution its no. of particles will remain same i.e. the no. of moles will be the same.
- Molarity = no. of moles/volume
- Therefore, no.of moles = Molarity×Volume
in case of dilution M₁V₁=M₂V₂
where M is molarity and V is volume
M₁=4.75M (Given)
V₁=3.4ml (Given)
M₂=? (To Find)
V₂=40ml (Given)
Put the values in the equation and see the magic.
