How many molecules of glycerol (C3H8O3; molecular mass = 92) are present in 1 L of a 0.5 M glycerol solution?

Question

Quizplus · Accepted Answer

0.5 M glycerol solution means there are 0.5 moles of glycerol in 1 L of the solution.

To calculate the number of glycerol molecules, we need to convert moles to molecules using Avogadro's number (6.02 × 10^23 molecules per mole).

Number of glycerol molecules = 0.5 M × 6.02 × 10^23 molecules/mole = 0.5 × 6.02 × 10^23 = 3.01 × 10^23 molecules

Therefore, the answer is B: 0.5 × 6.02 × 10^23.
