The amount of gas that occupies 72.9 L at 23.7 oC and 723 mmHg is
Ans :
The amount of gas can be calculated using the ideal gas law pV = nRT
where p is pressure = 723 mmHg = 0.951316 atm
V is volume = 72.9 L
T is temperature = 23.7oC = 296.85 K
R is universal gas constant = 0.0821 L.atm/mol.K
So putting all the values , we get :
0.951316 x 72.9 = n x 0.0821 x 296.85
n = 2.8 mol
So the amount of gas will be 2.8 mol.
