Question

A a solution contains 5.6 ml of alcohol mixed with 75 ml of water calculate the concentration of a solution
​

Answer 1

$\huge{\underline{\underline{\huge{\bold{AnsweR \: :-}}}}}$

Volume of water = 75 ml

Volume of alcohol = 5.6 ml

So, volume of solution = 75 + 5.6 = 80.6 ml

$\large \sf \: concentration \: =$

$\large\sf \color{red}\frac{volume \: of \: solute}{volume \: of \: solvent + volume \: of \: solute} \times 100$

$\large \sf = \frac{5.6}{80.6} \times 100$

$\large \sf \: = 6.9\%$
