Answer:
Option A. 1.14L
Explanation:
Data obtained from the question include:
V1 = 1.20 L
P1 = at stp = 760torr
T1 = at stp = 273K
P2 = 900torr
T2 = 35°C = 35 + 273 = 308K
V2 =?
Using P1V1/T1 = P2V2/T2, we can obtain the new volume as follows:
P1V1/T1 = P2V2/T2
(760 x 1.2)/273 = (900 x V2) /308
Cross multiply to express in linear form
273 x 900 x V2 = 760 x 1.2 x 308
Divide both side by 273 x 900
V2 = (760 x 1.2 x 308) /(273 x 900)
V2 = 1.14L
