Answer:
Explanation:
From the question we are told that:
Mass of mixture
Mass of Barium
Equation of Reaction is given as
Generally the equation for Moles of Barium is mathematically given by
Since
Therefore
Generally the equation for Mass of Barium is mathematically given by
Therefore
The density is 3.144 g / cm^3.
<u>Explanation</u>:
If effective number of atom in NaCl type structure, z = 4
a = 705.2 pm ⇒ In centimeter = 705.2 10^-10
Na = 6.023 10^23
density = (molecular weight) (z) / (Na) (a^3)
where molecular weight of KI is 166 g,
Z represents the atomic number
density = (molecular weight) (z) / (Na) (a^3)
= (166 4) / (6.023
10^23)
(705.2
10^-10)
density = 3.144 g / cm^3.
