Question

how many oxygen atoms are in the formula of magnesium nitrate, mg(no₃)₂? view available hint(s) 1 2 3 6

Explanation:

Step1: Analyze the nitrate ion

In the formula \(Mg(NO_3)_2\), the nitrate ion is \(NO_3^-\). Each nitrate ion contains 3 oxygen atoms.

Step2: Consider the coefficient

The coefficient 2 outside the parentheses \((NO_3)_2\) means there are 2 nitrate ions. So the total number of oxygen atoms is \(3\times2 = 6\).

Answer:

6
