Question

during an experiment the students were asked to prepare 10% (mass/mass) solution in water. ramesh dissolved 10g of sugar in 100g of water which sarika prepared it by dissolving 10g of sugar in water to make 100g of solution
(i) are the two solution of the same concentration ​

Answer 1

Answer:

No, the two solutions were of different concentrations.

Explanation:

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.
