QUESTION:
Determine the amount of sucrose in each solution.
(a) 48 g of a solution containing 3.7% sucrose by mass
(b) 103 mg of a solution containing 10.2% sucrose by mass
(c) 3.2 kg of a solution containing 14.3% sucrose by mass
ANSWER:
Step 1 of 3
Amount of sucrose present is,
(a) 48 g of a solution containing 3.7% sucrose by mass
Mass percent is the number of grams of solute per 100 g of solution. So a solution with 3.7 % of concentration of sucrose by mass contains 3.7 g of sucrose 100 g of solution.
Hence 48g of solution contains,
\(\frac{3.7\text{ g of sucrose }}{100}\times48\mathrm{\ g}\text{ solution }=1.8\mathrm{\ g}\text{ sucrose }\).
