What volume of CO2 will be delivered at NTP to extinguish the fire from a cylinder of 10 L? ( It contains 5Kg CO2 gas )

Here,

mass of CO₂ = 5kg = 5 × 1000 = 5000 g

Also we know that

At STP ,

44 g of CO₂ will produce 22.4 L of CO₂ gas.

5000g of CO₂ will produce (22.4 × 5000 ) / 44 L of CO₂ gas

= 2545.45 L

The volume of CO₂ that will come out is 2545.45 – 10 = 2535.45 L

Hence, the volume of CO₂ gas delivered is 2545.45 L.
