Dear student

w = 22g dry CO2 which will evaporate to develop P

m = 44

V = 0.6 litre

P = ?

T = 298 K

PV = wmRT

P×0.6=2044×0.0821×298


Pressure inside bottle = P + atm. pressure

w = 22g dry CO2 which will evaporate to develop P
m = 44
V = 0.75 litre
P = ?
T = 298 K
PV = wmRT
P×0.6=2044×0.0821×298
⇒ P = 8.334 atm
Pressure inside bottle = P + atm. pressure
⇒ 8.334 + 1 = 9.334 atm
