Question

12. During an experiment, the students were asked to prepare a 10%
concentration solution of salt in water. Rahul dissolved 10g of salt in 100g
of water while Priya prepared it by dissolving 10g of salt in water to make
100g of solution
a. Calculate the mass/mass percentage in each case.
b. Do the two solutions have same concentration
c. Whose measurements are correct for the experiment?
Who are lysosomes known as suicidal bags of a cell?​

Answer 1

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.
