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 formula of nitrate ion

In the formula \(Mg(NO_3)_2\), the nitrate ion is \(NO_3^-\). In one \(NO_3^-\) ion, there are 3 oxygen atoms.

Step2: Consider the number of nitrate ions

There are 2 \(NO_3^-\) ions in \(Mg(NO_3)_2\) (because of the subscript 2 outside the parentheses). So the total number of oxygen atoms is \(3\times2 = 6\).

Answer:

6
