When 1 L of $C O_{2}$ is heated with graphite, the volume of the gases collected is 1.5 L. Calculate the number of moles of CO produced at STP

Options:

Answer:

Solution:

$\underset{1 - x}{C O_{2} (g) + C (s)} \to \underset{2 x}{2 C O (g)}$
Total volume $= 1 + x = 1.5$
So $x = 0.5$ L
Volume of $C O = 2 \times 0.5 = 1$ L
Moles of $C O = \frac{1}{22.4}$ moles
