Question

a solution contain 25 ml of alcohol mixed with 75 ml of water calculate the concentration of solution​

Answer 1

SOLUTION

Volume of the solute(salt)= 25ml

Volume of the solvent(water)

=) 75ml volume of the solution

=) volume of the solute+ volume of the solvent = 25+ 75= 100 ml

Volume of percentage of solution

=) Volume of solute/volume of solvent×100%

$= > \frac{25}{100} \times 100 \\ \\ = > 25\%$

hope it helps ☺️

Answer 2

αnѕwєr--

vσlumє σf ѕσlutє=25 ml

vσlumє σf ѕσlvєnt=75 ml

vσlumє σf ѕσlutíσn=25+75=100 ml

ѕσ cσncєntrαtíσn σf ѕσlutíσn =

$\dfrac{volume \:of \: solute }{volume \: of \: solution} \times 100$

$\dfrac{25}{100} \times 100 = 25\%$
