Interpretation:
The empirical formula of the compound needs to be determined.
Concept introduction:
The empirical formula tells about the simplest ratio of atoms of present in the molecule. It does not give the actual number of atoms present in the molecule.
Answer to Problem 64PP
The empirical formula of the compound is
Explanation of Solution
Given information:
An oxide of potassium is decomposed in
Calculation: The mass of K and O is 19.55 g and 4.00 g respectively. The molar mass of K and O is 39.1 g/mol and 16 g/mol respectively.
The number of moles of K and O can be calculated as follows:
Thus,
The ratio of number of moles of K and O will be:
Thus, the empirical formula is
Therefore, the empirical formula of the compound is
