For the reaction SO2 + O2 --> SO3?

Question

how many grams of SO2 are needed to completely react with 64.00 g of O2 ?

Answer 1

2 SO2 + O2 --> 2 SO3


ok, 64.00 g oxygen times the molar mass of 02( 32.00) to get mols of O2 then time the mole ratio of O2 to SO2 which is (2 mol SO2/2 Mol O2) and then u have the mols of SO2 times that by the molar mass of SO2 to get the mass of SO2

64.00 x 32.00 x 2/2 x molar mass of SO2
