Sagot :

The molarity of the unknown solution will be 1.310 M.It is denoted by M₂.

What is molarity?

Molarity is defined as the ratio of the moles to the volume of the solution.

Given data;

Volume of unknown solution,V₁ = 10.5 mL

The volume of diluted solution,V₂ = 80.0 mL

Molarity of new solution,M₁ = 0.172 M

Molarity of unknown solution, M₂=?

For dilution we use the formula as;

M₁V₁=M₂V₂

M₂=M₂V₂/V₁

M₂ = ( 80 × 0.172 ) / 10.5

M₂= 1.310 M

Hence the molarity of the unknown solution will be 1.310 M.
