Question

question 11
the total number of atoms indicated by the formula na2co3 is

Explanation:

Step1: Analyze the formula

The formula \(Na_2CO_3\) contains \(Na\) (sodium), \(C\) (carbon), and \(O\) (oxygen) atoms.

Step2: Count each type of atom

• Sodium (\(Na\)): There are \(2\) \(Na\) atoms as indicated by the sub - script \(2\) next to \(Na\).
• Carbon (\(C\)): There is \(1\) \(C\) atom (since no sub - script implies \(1\)).
• Oxygen (\(O\)): There are \(3\) \(O\) atoms as indicated by the sub - script \(3\) next to \(O\).

Step3: Calculate the total number of atoms

The total number of atoms is \(2 + 1+3=6\).
