We can use the ideal gas law to solve for the number of moles:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.

Rearranging the equation, we get:

n = PV/RT

Substituting the given values:

n = (100 Pa)(0.0100 m^3)/(8.31 J/(mol*K) * 300 K)

n = 0.401 mol

Therefore, the answer is D) 0.401.
