Question

25. Which will have greater volume when the following gases
are compared at S.T.P.
(a) 1.2 1 N, at 25°C and 748 mm Hg
(b) 1.25 1 0, at S.T.P. ?
[Ans. (b)]
please help me to solve this problem the is given below​

Answer 1

Answer:Case a.

Use formula P1V1 /T1= P2V2/T2

P1= 748/760 atm   V1=1.2L T1 = 300K

P2= 1 atm   V2= ?   T2= 273K

V2 = (748 x 1.2 x 273)/(760 X 300)

   = 1.074L

Cae b. 1.25L of O2 at STP

Volume is greater for b.
