Answer:
%H = 6.72 %
Explanation:
Percent composition of an element is the total mass of that element divided by the molecular mass of compound (or molecular mass) of which it is present in.
So,
Percent composition of Hydrogen will be given as,
%H = Total mass of H / Molecular Mass of Acetic Acid × 100
So,
Total Mass of H = 1.01 × 4 = 4.04 g
Molecular Mass of Acetic acid = 60.052 g/mol
Putting values in above formula,
%H = 4.04 g/mol ÷ 60.052 g/mol × 100
%H = 6.72 %

Answer is: 4 atoms of nitrogen.
One formula unit of magnesium nitrate (Mg(NO₃)₂) has two atoms of nitrogen, so two formula units of magnesium nitrate will have four atoms of nitrogen (2·2=4).
Oxidation number of magnesium in magnesium nitrate is +2 and oxidation number of nitrate anion is -1 (2·(-1) = -2).
