Question

The total number of atoms in $2C_6{H}_{12}{O}_6$ is:

• A. is true and B is false.
• B. A is false and B is true.
• C. Both A and B are true
• D. Both A and B are false

Answer 1

The correct option is A

is true and B is false.

The 2 on the left side of the chemical formula represents the number of molecules. So if we count the total number of atoms in one molecule, then it comes out to be 6C + 12H + 6O = 24 atoms. Now, as there are two molecules, we have 2 x 24 = 48 atoms in total.
