Answer : The number of moles of argon gas is, 11.5 mol

Explanation :

To calculate the moles of argon we are using ideal gas equation as:

where,

P = pressure of argon gas = 658 mmHg = 0.866 atm    (1 atm = 760 mmHg)

V = volume of argon gas = 30.6 L

n = number of moles of argon gas = ?

R = gas constant = 0.0821 L.atm/mol.K

T = temperature of argon gas = 28 K

Now put all the given values in the above formula, we get:

Therefore, the number of moles of argon gas is, 11.5 mol
