Answer:

No. of moles, n = 25.022 moles

Given:

Volume of gas in tank, V = 29.1 l

Temperate of gas, T = [tex]35.8^{\circ}[/tex] = 273 + 35.8 = 308.8 K

Pressure of gas, P = 21.8 atm

Solution:

Making use of the ideal gas equation which given as:

PV = nRT

where

R = Rydberg's constant = 0.0821 L-atm/mol-K

Re-arranging the above formula for 'n' and putting the values in the above formula:

[tex]n = \frac{PV}{RT}[/tex]

[tex]n = \frac{21.8\times 29.1}{0.0821\times 308.8}[/tex]

n = 25.022
