Concept explainers
Interpretation: The empirical formula of compound with given mass percentage of elements needs to be determined.
- Ba = 58.84 %
- S = 13.74 %
- O= 27.43 %
Concept Introduction: The molecular mass of compound is the sum of
Whereas empirical formula can be defined as the simplest positive integer ratio of all bonded atoms in the compound.
Answer to Problem 37A
The empirical formula must be
Explanation of Solution
Given information:
Ba = 58.84 %
S = 13.74 %
O = 27.43 %
Mass percentage of Ba = 58.84 %
Mass percentage of S= 13.74%
Mass percentage of O = 27.43 %
Calculate moles of each with the help of atomic mass:
Divide by least moles to get the whole number ratio:
Thus the empirical formula must be
The empirical formula must be
