What would be the resulting concentration if enough water is added to 350.0 mL of a 0.650 M solution to bring it up to 750 mL in volume

Answer 1

M₁V₁ = M₂V₂

M₁ = 0.650 M, V₁ = 350.0 mL, V₂ = 750.0 mL, M₂ = ?

(0.650 M)(350.0 mL) = M₂(750.0 mL)

227.5 M(mL) = M₂(750.0 mL)

M₂ = 0.303 M

The resulting concentration is 0.303 M
