Question

choose the correct example.

mg(c₂h₃o₂)₂, the number of h atoms is 6

mg(c₂h₃o₂)₂, the number of h atoms is 3

mg(c₂h₃o₂)₂, the number of h atoms is 5

mg(c₂h₃o₂)₂, the number of h atoms is 2

Explanation:

Step1: Analyze the sub - script of H in the formula

In the formula \(Mg(C_2H_3O_2)_2\), the sub - script of H within the parentheses is \(3\).

Step2: Consider the multiplier outside the parentheses

The multiplier outside the parentheses is \(2\).

Step3: Calculate the total number of H atoms

Multiply the sub - script of H (\(3\)) by the multiplier (\(2\)): \(3\times2 = 6\)

Answer:

\(Mg(C_2H_3O_2)_2\), the number of H atoms is \(6\)
