How many carbon atoms are in a molecule of table sugar [tex]\left( C _{12} H _{22} O _{11}\right)[/tex]?

A. 11
B. 12
C. 45
D. 22

Sagot :

To determine the number of carbon atoms in a molecule of table sugar, we need to examine its molecular formula, which is [tex]\( C_{12}H_{22}O_{11} \)[/tex].

In this formula:
- [tex]\( C \)[/tex] stands for carbon.
- The subscript number following [tex]\( C \)[/tex] tells us the number of carbon atoms in one molecule of the compound.

Here, the subscript following [tex]\( C \)[/tex] is 12. This indicates there are 12 carbon atoms present in one molecule of table sugar.

Therefore, the number of carbon atoms in a molecule of table sugar is:

[tex]\[ \boxed{12} \][/tex]

The correct answer is B. 12.
