Question

38 ml of gas collected at 27°C & 746.5 mm pressure . Calculate the volume of gas at 0°C & 760 mm pressure.

Answer 1

(P1×V1)/T1 = (P2×V2)/T2

Given, P1= 746.5mm ; V1= 38ml ; T1= 27°C = 27+273= 300 K ; P2= 760mm ; T2=0°C = 273K

Putting these values in above formula, we get

V2= (P1×V1×T2)/(T1×P2) = (746.5 × 38 × 273)/(300 × 760)≅ 352.46 ml
