We can solve this problem using the ideal gas law:
PV = nRT

where P is the pressure in atm, V is the volume in L, n is the number of moles, R is the gas constant, and T is the temperature in K.

First, we need to convert the temperature to K:
22°C + 273.15 = 295.15 K

Now we can solve for n:
n = PV/RT

Plugging in the values we have:
n = (105 atm)(10.0 L) / (0.08206 L atm/mol K)(295.15 K)
n = 43.4 mol

Therefore, the answer is D, 43.4 mol.
