J. 24 g of carbon reacts with some oxygen to make 88 grams of carbon dioxide. Find out how much oxygen must have been used.

Answer 1

Given :: mass of Carbon = 24 g , mass of carbon dioxide =88g

Find : mass of oxygen 

Solution ::

$\begin{array}{ccc}C& +O_2& \to C{O}_2\\ 24g& ?& 88g\end{array}$ 

$\therefore$ mass of oxygen = mass of carbon dioxide - mass of carbon

=88-24 = 64 g

mass of oxygen used in this equation is 64 g
