Question

(b) During an experiment the students were asked to prepare a 20% (mass/mass) solution of sugar in water. Ram dissolved 20g of sugar in 1 oog 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.
