When $3.0 g$ of carbon is burnt in $8.00 g$ oxygen, $11.00 g$ of carbon dioxide is produced? What mass of carbon dioxide will be formed when $3.00 g$ of carbon is burnt in $50.00 g$ of oxygen? Which law of chemical combination will govern your answer?

Solution

$C + O_{2} \to C O_{2}$
$3 g$ $8 g$ $11 g$
Total mass of reactants = mass of carbon + mass of oxygen $= 3 + 8 = 11 g$
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 $(50 - 8) = 42 g$ of oxygen will remain unreacted.
