Propane, C3Hg, is the fuel in barbecue tanks, Calculate the volume that 4.5 mol of propane occupies at STP.

Answer 1

The fertilizer ammonium sulfate, (NH4)2SO4, is prepared by the reaction of ammonia, NH3, with sulfuric acid: 2 NH3 (g) + H2SO4 (aq)  (NH4)2SO4 (aq)

How many moles of ammonium sulfate are produced if 1.50 moles of ammonia react completely at STP? Answer: The balanced equation indicates that 2 moles of NH3 react to produce 1 mole of (NH4)2SO4.

1.50 moles NH3 x 1 mol (NH4)2SO4 = 0.750 moles (NH4)2SO4
