Question:

The initial abundances of O, Mg, and Si atoms are respectively in the ratio 21:1:1.
And O, Mg, and Si respectively have atomic masses of 16, 24, and 28 a.m.u.

Assuming a planet is made of olivine minerals (Mg2SiO4), how many O atoms are left over for every 2 Mg atoms used?

Assuming the extra O atoms combine with hydrogen to form H2O, what is the mass ratio of water to rock on this planet?
