How many moles of hydrogen are in a sample of octane, C8H18, that contains 303.9 grams of carbon

List the 4 quantum #s for the 32nd e- of cesium, I know that n = 4, and l = 1. However, can the magnetic quantum number equal -1, 0, or 1? There is no way to assign these numbers to the px, py, pz orbitals? And can the spin magnetic quantum number be either +1/2 or -1/2?
