How Many Molecules of Glycerol Would Be Present in 1

Question

How many molecules of glycerol would be present in 1 L of a 1 M glycerol solution?
A)1 × 10⁶
B)14 × 6.02 × 10²³
C)92 × 6.02 × 10²³
D)6)02 × 10²⁶
E)6)02 × 10²³

Accepted Answer

1 M glycerol solution means there is 1 mole of glycerol in 1 liter of solution. The molecular weight of glycerol is 92. Therefore, the number of molecules of glycerol in 1 L of 1 M solution would be:
1 mole glycerol = 6.02 × 10²³ molecules which is also called Avogadro's number 
So, 1 L of 1 M glycerol solution would contain 6.02 × 10²³ molecules of glycerol.
