300g of mg is burned on fire to produce magnesium oxide. final product weighs 4.97. what is the empirical formula for magnesium oxide?
On the (guessed) data we would plump for
The empirical formula is the simplest whole number ratio defining constituent atoms in a species... And so we interrogate the moles of magnesium and oxygen in the given problem.
And thus there are equimolar quantities of magnesium and oxygen in the given mass so we gets...an empirical formula of
...to do this formally we have...
