Question

what is the concentration of a solution prepared by mixing 5.00 ml of deionized water with 3.00 ml of a 1.31 m solution? report your answer in moles/liter, but do not include units in your answer.

Answer 1

The equation M1V1 = M2V2 is used to solve problems related to dilution in chemistry

Given data in the question

intial concentration = 1.31 M

final concentration = ?

initial volume = 3 ml

final volume = 3ml + 5ml = 8 ml

Now we know that

M1V1 = M2V2

where

M1 initial concentration

M2 = concentration after mixing or diluting

V1 initial volume,

V2= total final volume

The equation M1V1 = M2V2 is used to solve problems related to dilution in chemistry

What is dilution?

It is process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to solution.

M1V1 = M2V2

M2 = ( M1V1 ) / V2 = ( 1.31 × 3 )/ 8 = 0.491 mol/l
