in the formula MgO, what is the relative mass ratio of magnesium to oxygen? what is "count ratio" of magnesium to oxygen in MgO? why are the two ratios different?
Homework Answers
Count ratio is obtained by dividing the number of Mg atoms in one formula unit of MgO with number of oxygen atoms.
This ratio is different from relative mass ratio of magnesium to oxygen due to difference in atomic masses of magnesium and oxygen
The atomic masses of magnesium and oxygen are 24.3 g/mol and 16 g/mol respectively.
The relative mass ratio of magnesium to oxygen in the formula MgO is
