Q
explain the method for calculating empirical formula
A
1) measure the mass of the solid that is going to be reacted
2) react the solid with the oxygen in the air by heating
3) find out the mass of the product
4) calculate the mass of oxygen gained ( initial - final )
5) use the mass of magnesium and oxygen to calculate the empirical formula
