In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.
Answer:
The Chemical formula of sodium is Na.
The Chemical formula of oxide is O.
Explanation:
Therefore we know that the term 'valency' is called as the combining capacity of an atom of an element.
So by taking the valency of Sodium and Oxide, we get
Sodium with valency '1' and Oxide with valency '2'.
Na O
1 2
When you cross over you get 'Na2O' as the formula for sodium oxide.

TY.
80.5%- The total mass of the compound is 18g (14.5 + 3.5) then divide the mass of magnesium by the total. easy way to remember is- (part/whole) x 100
A. The reactants that run out first
Easy!
