Answer:
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
Explanation:
Percent yield is calculated by obtaining the ratio of the actual yield and the theoretical yield times 100.
Actual yield = 1500 kg
Theoretical yield = 1500 ( 1 / 30.00 ) ( 2 / 2 ) ( 46.006 / 1 ) = 2300.3 kg
Percent yield = 1500 / <span>2300.3</span> x 100 =<span> 65.21 %
Therefore, the correct answer is the last option. Hope this answers the question.</span>
