Question- a) What volume of fluorine (F2), measured at STP, would be needed to react with 84 grams of sulfur (S) according to this reaction:
S + F2 ----> SF6 (atomic wts: F=19,S=32)
b) The weight of 151ml of a certain vapor at 68 degrees C and 768mm is 1.384g. What is the molecular weight of the vapor?
