Question

Calculate the masses of cane sugar and water required to prepare 250 grams of 25% cane sugar solution-

• A. 187.5 grams, 62.5 grams
• B. 62.5 grams, 187.5 grams
• C. 162.5 grams, 87.5 grams
• D. None of these

Answer 1

Answer: (B)

Mass percentage of sugar = 25
We know that
Mass percentage $=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$
So, $25=\frac{\text{Mass of cane sugar}}{\text{250}}\times 100$
or Mass of cane sugar $=\frac{25\times 250}{100}=62.5$ grams
Mass of water $=\left(250-62.5\right)=187.5$ grams
