Answer 3

I don't know chemistry, just give you the logic to do it in Math
now balance the equation:\(Mg +\frac{1}{2}O_2\rightarrow MgO\) to me, it means 1g Mg with react with 1/2 g O,
we have 125 g Mg, so we need 62.5 g O, the whole thing must weigh 125+62.5 = 187.5g MgO
hehehe. I am joking, wait for Chemistry student.
