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.

David Ramsey and James Winthrop differ completely towards the principle of representation in the United States,<em> they only agreed in the Bill of Rights</em>.
On one side David Ramsey, who is a federalist, believes the whole country should be governed by the same laws made by the legislation. On the other side James Winthrop is an anti federalist who believed that one of the reasons freedom in America was presereved was because the states have the right to be self-governed.
