3g 8g 11g
Total mass of reactants = mass of carbon + mass of oxygen =3+8=11g
Total mass of reactants = Total mass of products
Hence, the law of conservation of mass is proved.
Further, it also shows carbon dioxide contains carbon and oxygen in a fixed ratio by mass, which is 3:8.
Thus it also proves the law of constant proportions. 3 g of carbon must also combine with 8 g of oxygen only.
This means that (50−8)=42g of oxygen will remain unreacted.
