for 12 vol.s of o2 the same vol. of co2 is produced.
hence, c.250 litres

Answer: c. 250 liters

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number
6.023* 10^(23) of particles.

To calculate the moles, we use the equation:


\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}


\text{Number of moles of oxygen}=(250L)/(22.4L)=11.16moles

Now 12 moles of
O_2 gives= 12 moles of
CO_2

11.6 moles of
O_2 gives=
(12)/(12)* 11.6=11.6moles

Volume of
CO_2=moles* {\text {Molar volume}}=11.6* 22.4=250L
