Question

Calculate the volume of a gas 'A' at s.t.p., if at 37°C and 775 mm of mercury pressure, it occupies
a volume of 9 and a half.​

Answer 1

V1= 9(1/2)L =9/2 L

P1=775mm. P2=760 mm

T1=273+37=310 K

T2 = 273 K

V2=?

------- = -----------

T1. T2

V2=------------

T1 P2

V2=(775×4.5×273)/(310×760)

V2=8.53 L
