How many molecules of glucose are in 5.72 grams of glucose?

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

5.72 g ( 1 mol / 180.16 g ) (  6.022 x 10^23 molecules / mole ) = 1.90x10^23 molecules

Ithink it’s 3 as the answer.
