Question

at 400K temperature 200ml N2 has pressure 1.5bar find the volume of N2gas as STP

Answer 1

Explanation:

this is just a direct formula that is

PV=nRT

so pressure is 1.5 bar that is nearly equals to 1.5 atm

volume is 200 ml that is 0.2 litres

and temperature is 400 Kelvin

so no of moles will be 0.009 so the volume contained at stp will be (0.009 × 22.4) litres that is 0.2016 litres or 201.6 ml
