Question

Answer 1

Answer:

fyi Dr th U.S. e.g. https https every etch ***tfdtg

Answer 2

V1 = 90 litre

mass(m) = 10 g

at NTP

T1 = 273 K

P1 = 1 atm

T2 = 273 + 200 = 473 K

V2 = ?

Charle's law :

V1/T1 = V2/T2

V2 = 155.93 L

escaped volume = 155.93 - 90 = 65.93 L

mass of escaped gas = 1/9 * 65.93 = 7.335 gm
