Question

how many atoms of oxygen are in the chemical formula for potassium carbonate? 2k₂co₃

Explanation:

Step1: Analyze the formula \(2K_2CO_3\)

In the formula \(K_2CO_3\), the subscript of O is 3, which means there are 3 O atoms in one \(K_2CO_3\) molecule.

Step2: Calculate the number of O atoms in \(2K_2CO_3\)

The coefficient 2 in front of \(K_2CO_3\) means there are 2 molecules of \(K_2CO_3\). So the total number of O atoms is \(2\times3 = 6\).

Answer:

6
