1) What is the mass of 38 molecules of SO₃ in g?

2) What volume in L of chlorine at 30^oC and 743 torr is required to react completely with 4.76 g aluminum:

2Al(s) + 3Cl₂(g) → 2AlCl₃(s)

Calculate the moles chlorine needed (as in the previous problem), then use the ideal gas law--PV = nRT. Additional help is given in the feedback.
