2500 cm3 of hydrogen is taken at S.T.P.The pressure of this gas is further increased by two and a half times (temperature remaining Constant). What volume will hydrogen occupy now? Looking to do well in your science exam ? Learn from an expert tutor. Book a free class!

V1 = 2500 cm3

P1 = 1 atm = 760 mm

T1 = 273 K

V2=?

T2 = 273 K

P2 = 760 x 5/2 + 760

= 1900 + 760 = 2660 mm

P1V1/T1= P2V2/T2

V1 = 2500 cm3

P1 = 1 atm = 760 mm

T1 = 273 K

V2=?

T2 = 273 K

P2 = 760 x 5 + 760

2

= 1900 + 760 = 2660 mm

P1V1 /T1= P2V2/T2

760 x 2500/273 = 2660 x V2/273

V2 = 5000/7 = 714.29 cm3
