Question

given the molar ratio of chlorine to oxygen in the sample, what number x can we use as a multiplier to get a whole number integer for both elements?

3
5
4
2

Explanation:

Step1: Analyze the molar ratio

The molar ratio of \(Cl:O = 1:3.5\).

Step2: Find the multiplier

To convert \(3.5\) (a non - integer) to an integer, we know that \(3.5\times2=7\) (an integer) and \(1\times2 = 2\) (an integer).
