Interpretation:The empirical formula of two binary compounds of nitrogen and sodium with given percentage of the elements needs to be determined.
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 43A
Compound 1 =
Compound 2 =
Explanation of Solution
Compound 1:
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
Compound 2:
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
Sodium can form two types of nitrogen containing binary compounds.
