Answer : The value of the gas constant is, [tex]62.4\text{ mmHg.L/mol.K}[/tex]
Explanation :
Using ideal gas equation:
PV = nRT
where,
P = pressure of gas = 930 mmHg
V = volume of gas = 20.0 L
n = number of moles of gas = 1 mol
T = temperature of gas = [tex]25^oC=273+25=298K[/tex]
R = gas constant = ?
Now put all the given value in the above formula, we get:
[tex]930mmHg\times 20.0L=1mol\times R\times 298K[/tex]
[tex]R=62.4\text{ mmHg.L/mol.K}[/tex]
Therefore, the value of the gas constant is, [tex]62.4\text{ mmHg.L/mol.K}[/tex]
