Answer:
The cylinder is nit on the verge of exploding.
Step-by-step explanation:
Temperature= 25.0°C
The conversion of T(°C) to T(K) is shown below:
T(K) = T(°C)+ 273.15
So,
T=(25.0 + 273.15) K = 298.15 K
Volume= 4.50 L
Moles= 40.0 mol
Using ideal gas equation as:
PV = nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is gas constant having value = 0.0821 Latm/ K. mol x 298.15 K
⇔ P= 217.58 atm
Pressure limit = 500 atm .
