Answer:
d) 60%
Explanation:
Given the chemical formula;
MgO = Magnesium oxide.
First of all, we would determine the relative molecular mass (RMM) of MgO.
Atomic mass of Mg = 24
Atomic mass of O = 16
RMM (MgO) = 24 + 16 = 40 g/mol
Next, we would find the percent by mass of magnesium (Mg);
% Mg = 24/40 * 100
% Mg = 2400/40
% Mg = 60 percent.
