Answer:
The percentage is k %
Explanation:
From the question we are told that
The mass of the stibnite is
The volume of KBrO3(aq) is
The concentration of KBrO3(aq) is
Now the balanced ionic equation for this reaction is
The number of moles of is
substituting values
from the reaction we see that 1 mole of reacts with 3 moles of
so 0.003325 moles will react with x moles of
Therefore
Now the molar mass of is a constant with a values of
Generally the mass of is mathematically represented as
substituting values
The percentage of Sb(antimony) in the overall mass of the stibnite is mathematically evaluated as
k
k %
