How many atoms of carbon are present in 1.80 g sample of glucose, C6H12O6?

I got as far as converting the g of glucose to 1.08x10^23 atoms glucose and I don't know how to get the number of carbon atoms out of that.  It's not 6 either....

1.08x10^23 atoms glucose

No such thing as glucose atom, there are only glucose molecules.

How did you get this number? It is wrong.

sample of glucose i meant

[Korokian]

and that link didn't help me... i'm trying to find the number of atoms of carbon

[Dan]

1. How many moles of glucose are there? hint: what is the relative molecular mass of glucose?
2. How many carbon atoms are there in one molecule of glucose?
3. So how many moles of C atoms are there in one mole of glucose molecules?
4. So how many moles of C atoms are there in [your answer to 1]  moles of glucose molecules?

[Korokian]

1. 0.10 mol glucose
2. 6 carbon atoms to one molecule of glucose
3. 6 moles carbon to one mole of glucose
4. 3.61x 10^22 Carbon atoms?

1. 0.10 mol glucose
2. 6 carbon atoms to one molecule of glucose
3. 6 moles carbon to one mole of glucose
4. 3.61x 10^22 Carbon atoms?

Yes x 4
