Question

How many carbon atoms are in four molecules of glucose, or 4c6h12o6?

Answer 1

One can find there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in one molecule of glucose. Hope this helps :) Have a great day :) Remember to always be positive :) 

Answer 2

Answer: 12 carbon atoms

Explanation:

Atom is the smallest unit of matter which may or may not have independent existence. Example: $N$

Molecule is the smallest unit of matter which has a independent existence.Example: $N_2$

1 molecule of $C_6H_{12}O_6$ has 6 atoms of carbon

Thus if 1 molecule of $C_6H_{12}O_6$ has carbon atoms = 3

4 molecules of $C_6H_{12}O_6$ has total of =$\frac{3}{1}\times 4=12atoms$

Thus there are 12 carbon atoms in four molecules of glucose.
