Question

During an experiment the students were asked to prepare a 10% (Mass/Mass) solution of sugar in water. Ramesh dissolved 10g of sugar in 100g of water while Sarika prepared it by dissolving 10g of sugar in water to make 100g of the solution. What is the mass percentage of solution prepared by Ramesh and Sarika?

• A. 9.09%, 9%
• B. 9%, 10%
• C. 10%, 9.09%
• D. 9.09%, 10%

Answer 1

Answer: (D)

9.09%, 10%

$masspercent=\frac{Massofsolute}{Totalmassofsolution}\times 100$

Solution prepared by Ramesh is:

Mass % $=$ $\left(\frac{10}{10+100}\right)100=\frac{10}{110}\times 100=9.09$ %
Solution made by Sarika is:
Mass % $=\frac{10}{100}\times 100=10$%
The solution prepared by Sarika has a higher mass % than that prepared by Ramesh.
