Interpretation:
The empirical formula of propane needs to be determined if it contains
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 60PP
The empirical formula is
Explanation of Solution
Given Information:
The compound has
Calculation:
Assume the total mass of compound is 100 g thus, mass of C and H atom will be 81.82 g and 18.18 g respectively.
The molar mass of C and H is 12 g/mol and 1 g/mol respectively. Thus, moles of C and H can be calculated as follows:
And,
To determine the simplest ratio, divide number of moles of C and H with smaller number of moles that is number of moles of C.
Thus,
Thus, empirical formula of compound is
The empirical formula of propane is
