Question

a solution of acetine contain 30ml of acetone in 570ml of water calcuata the percentage concentration if the solute in the solution

Answer 1

percentage of concentration =
=(volume of solute/volume of solutions )×100

=(30/570)×100

=(3/57)×100

=(1/19)×100

=100/19

=15.6
will be the concentration of acetein in solution of water.

Answer 2

hey friend !!!!

definition of % v/v = volume of solute / volume of solution *100

In this case:
Total volume = 570mL

then percentage concentration =
= (30×100)/570 = 100/19 = 5.623%

hence your answer is "5.623%"

I think my answer is capable to clear your confusion
