Question

At 400 K temperature, 200 ml N2 has pressure 1.5 bar. Find the volume of N2 gas at STP.​

Answer 1

we know

PV = nRT

P = 1.5 Bar = nearly 1.5 atm

V = 200ml = 0.2 liter

T = 400 K

number of moles will 0.009

so, the volume contain at STP will be

(0.009 × 22.4) lit

= 0.2016 lit

= 201.6 ml
