Answer:
The answer of a is 5.45% and b is 3.64%
Explanation:
Density of water = 1 g/mL
∴ Mass of water (solvent) = 500 g
Mass of solute (glucose) = 30 g
Mass of solute (common salt) = 20g
Mass of solution = (30 + 20 + 500) g = 550 g
<h2>a.) </h2>
Mass percentage of solution for glucose
= Mass of solute (gucose)/Mass of solution × 100
= 30/550 x 100
= 5.45 %
<h2>b.) </h2>
Mass percentage of solution for common salt
= Mass of solute (common salt)/Mass of solution × 100
= 20/550 × 100
= 3.64 %
Thus, The answer of a is 5.45% and b is 3.64%
