In an osmosis experiment, a semipermeable membrane separates two solutions: Side A contains 0.1 M glucose, and Side B contains 0.5 M glucose. Which side has the higher concentration of glucose?

• A. Side B
• B. Side A
• C. Both sides have equal concentration

Answer: (A)

Verified step by step guidance

1. Identify the concentrations of glucose on both sides of the semipermeable membrane: Side A has 0.1 M glucose, and Side B has 0.5 M glucose.
2. Recall that molarity (M) is a measure of concentration defined as moles of solute per liter of solution, so a higher molarity means a higher concentration of solute.
3. Compare the two given molarities directly: 0.1 M (Side A) versus 0.5 M (Side B).
4. Since 0.5 M is greater than 0.1 M, Side B has the higher concentration of glucose.
5. Understand that in osmosis, water tends to move from the side with lower solute concentration (Side A) to the side with higher solute concentration (Side B) through the semipermeable membrane.
