Question

11. Find the percent of concentration when 20 g of sugar is mixed in 60 g of wa more grams of sugar has to be added to make it a 40% solution.​

Answer 1

Answer:

Amount of sugar,40%of the solution will have =40/100×60

=24 gms

Amount of sugar that was mixed in the water at the initial stage= 20

=4 gms

Therefore the concentration percentage will be 4/20×100 %

=1/4×100 %

=25 %
