How many milliliters of 2.0 m nacl solution would you need to make 250 ml of 0.15 m solution

18.75 mL of NaCl solution is required.

Explanation:

Given data:

Molarity of solution one = 2.0 M

Volume of solution one = ?

Molarity of second solution = 0.15 M

Volume of second solution = 250 mL

Solution:

M₁V₁ = M₂V₂

V₁ = M₂V₂/M₁

V₁ = 0.15 M × 250 mL /  2.0 M

V₁ = 37.5 M.mL /  2.0 M

V₁ = 18.75 mL
