Answer 1

Answer:

OK by the way you compete with me then I will follow you but you can not

Answer 2

Answer:

(a) No, they are not of the same concentration

(b) The mass of the solution prepared by Sarika is higher than the mass of the solution prepared by Ramesh

Explanation:

(a) Mass% = Mass of Solute÷ Mass of Solution ×100

As the mass of the solution prepared  by Ramesh is higher than the mass of solution prepared by Sarika, the result is not same

(b) Ramesh's solution

solute = 10g

solution = solute + solvent = 10g + 100g = 110g

10÷110×100 = 9.09%

Sarika's solution

solute = 10g

solution = 100g

Mass% = 10÷100×100 = 10%
