If 100 mL of a 1.0 M solution is evaporated to a
volume of 25 mL, what will be the concentration
of the resulting solution?
(1) 0.25 M (2) 0.50 M (3) 2.0M (4) 4.0 M
20 Mbot is the

4. 4.0 M is the concentration of the resulting solution

Explanation:

As per the law of Volumetric analysis, we have the formula, V₁M₁= V₂M₂

V₁, M₁ are the volume and concentration of known solution, where as V₂, M₂ are the volume and concentration of unknown solution respectively.

Plugin the values to find M₂ as,

M₂ = V₁M₁ / V₂ = 100 × 1 / 25 = 4. 0 M

So  4.0 M is the answer.
