Question

When 1 L of CO2 is heated with graphite, the volume of the gases collected is 1.5 L. Calculate the number of moles of CO produced at STP (A) (1/11.2) (B) (28/22.4) (C) (1/22.4) (D) (14/22.4)

underset1 - xC O2 (. g .) + C (. s .) arrow underset2 x2 C O (. g .) Total volume =1+x=1.5 So x=0.5 L Volume of CO=2× 0.5=1 L Moles of CO=(1/22.4) moles

Q. 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

$\frac{1}{11.2}$

$\frac{28}{22.4}$

$\frac{1}{22.4}$

$\frac{14}{22.4}$

$1 - x C O_{2} (g) + C (s) \to 2 x 2 CO (g)$

Total volume $= 1 + x = 1.5$

So $x = 0.5$ L

Volume of $CO = 2 \times 0.5 = 1$ L

Moles of $CO = \frac{1}{22.4}$ moles
