Question

What mass of sucrose (C₁₂H₂₂O₁₁) in g is in 355 mL (12 floz) of a soft drink that is 11.5% by mass? (Assume a density of 1.04 g/mL)

a) 41.9 g
b) 38.7 g
c) 32.4 g
d) 25.6 g

Answer 1

To find the mass of sucrose in the soft drink, you can use the formula Mass = Volume × Density × Concentration. By substituting the given values, the mass of sucrose in the soft drink is approximately 0.0425 g.

Step-by-step explanation:

To find the mass of sucrose in the soft drink, we can use the formula:

Mass = Volume × Density × Concentration

First, we convert the volume from mL to L by dividing by 1000: 355 mL ÷ 1000 = 0.355 L. Then, we multiply the volume by the density to find the mass of the soft drink: 0.355 L × 1.04 g/mL = 0.3692 g. Finally, we multiply the mass of the soft drink by the concentration to find the mass of sucrose: 0.3692 g × 0.115 = 0.0425 g.

Therefore, the mass of sucrose in the soft drink is approximately 0.0425 g.
