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

Glucose is a carbohydrate having chemical formula C₆H₁₂O₆. The molecular mass of glucose is 180.12 grams.

Given that:

The molecular mass of 1 mol of Glucose = 180.12 grams

Given the mass of Glucose = 5.72 grams

Let the a be a number of moles present 5.72 grams, such that:

180.12 a = 5.72

a =

a = 0.03 moles

Now, from avogadro's constant, we know that:

1 mol =

0.03 mol = = molecules

Thus, the number of molecules in the 5.72 grams is molecules.
