<u>Answer:</u> The mass percent chlorine in pure chloride compound is 56.31 %.
<u>Explanation:</u>
We are given:
Mass of AgCl precipitated = 1.3487 g
We know that:
Molar mass of AgCl = 143.32 g/mol
Molar mass of Chlorine atom = 35.45 g/mol
As, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.
To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:
In 143.32 g of silver chloride, mass of chlorine present is 35.45 g
So, in 1.3487 g of silver chloride, mass of chlorine present will be =
To calculate the percentage composition of chlorine in pure chloride compound, we use the equation:
Mass of pure chloride compound = 0.5922 g
Mass of chlorine = 0.3335 g
Putting values in above equation, we get:
Hence, the mass percent chlorine in pure chloride compound is 56.31 %.
