Answer:
Mole percent of water in azeotrope is 69%
Explanation:
Clearly, the azeotrope consists of water and perchloric acid.
So, 72% perchloric acid by mass means 100 g of azeotrope contains 72 g of perchloric acid and 28 g of water.
Molar mass of water = 18.02 g/mol and molar mass of perchloric acid = 100.46 g/mol
So, 72 g of perchloric acid = of perchloric acid = 0.72 mol of perchloric acid
Also, 28 g of water = of water = 1.6 mol of water
Hence total number of mol in azeotrope = (1.6+0.72) mol = 2.32 mol of azeotrope
So, mole percent of water in azeotrope = [(moles of water)/(total no of moles)]%
Mole percent of water = % = 69%
Answer:
Given theoretical yield of NH3 is 945g.
The actual yield is 598g.
What is the %yield?
Explanation:
%yield of a chemical reaction can be calculated by using the formula:
Substitute the given values in this formula to get the %yield.
Hence, the %yield for the formation of ammonia is ---- 63.3.
