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

Each molecule of Glucose has 6 Carbon atoms, 12 Hydrogen atoms and 6 Oxygen atoms
So, the molecular mass of glucose is 6(12) + 12(1.01) + 6(16) = 180.12
If 1 mole of glucose has a mass of 180.12, then let x  be the number of moles of glucose that weighs 5.72 grams

180.12(x) = 5.72

So, to get x, we divide 5.72 by 180.12
5.72/180.12 = 0.03 moles

1 mole of any substance has around 6.022 x 10^23 molecules of the atom/molecule/ion

So 0.03 moles has (6.022 x 10^23) x 0.03 = 1.922 x 10^22 molecules

Don't hesitate to ask if you have any questions
Hope I helped xx

It was ernest rutherford

Sorry i dont understand the question can you rephase it?
