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.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
