Answer:
Step-by-step explanation:
Here, we want to get the pressure of the tank
To get this, we use the ideal gas equation as follows
Mathematically:
Where:
P is the pressure which we want to calculate
V is the volume which is 20 L
n is the number of moles which is 8.20
T is the temperature that we have to convert to Kelvin by adding 273 (53 + 273 = 326 K
R is the molar gas constant which is 0.0821 L.atm/mol.K
Substituting the values, we have it that:
