If a gas occupies a container of volume 146 cm3 at 18°C and 0.97`atm, its volume 146cm3 at s.t.p is?
-
A.
133 -
B.
146 -
C.
266 -
D.
292
Correct Answer: Option A
Explanation
V1 = 146cm3 T1 = 273 + 118 = 291 k
P1 = 0.971 atmosphere
V2 = ? T2 = 273K P2 = 1 atom
V2 = (0.971 atom χ 146cm3 χ 273k)/(1atm χ 291k) = 132997 0r = 133cm3
