Explanation:
The given reaction will be as follows.
Molar mass of = 122.5 g/mol
Molar mass of KCl = 74.5 g/mole
Molar mass of = 32 g/mole
We assume that the mass of in the sample be x g
Therefore, the mass of KCl in the sample = 0.95 - x
Hence, moles of =
So, moles of KCl produced = moles of =
or, mass of KCl produced =
Therefore, total mass of KCl = mass of residue = (0.95 - x) + = 0.820 g
-0.39x = 0.820 - 0.95
x = 0.33
Thus, % of in the original sample will be calculated as follows.
= 34.73%
Thus, we can conclude that mass % of is 34.73%.
