Question

During an experiment the students were asked to prepare a 20% (mass/mass) solution of sugar in water. Ram dissolved 20g of sugar in 100g of water while Sam prepared it by dissolving 20g of sugar in water to make 100g of the solution. Whose method of preparation produced 20% (mass/ mass) solution of sugar?​

Answer 1

Answer:

No, the two solutions were of different concentrations.

Mass%=

(massofsolute+massofsolvent)

massofsolute

×100

Solution made by Ramesh-

Mass%=

(100+10)

10

100=

110

10

×100=9.09%

Solution made by Sarika-

Mass%=

100

10

×100=10%

∴ Both have different concentrations.
