If 0.2 g of a substance is dissolved in 100 mL of solution, what volume V in litres should be used in the osmotic-pressure method?
Answer and explanation
Correct answer: 0.10 L
The osmotic-pressure equation must use a consistent volume unit. Since 1 L equals 1000 mL, the given volume is converted as V = 100 mL × (1 L/1000 mL) = 0.100 L. Thus, the correct choice is 0.10 L, option B. The mass of solute does not affect this particular unit conversion; only the stated solution volume is converted.
