Solution 99P
A compound containing carbon and hydrogen has a molar mass of 56.11 g/mol and an empirical formula of CH2. Determine its molecular formula.
It represents the actual number of atoms of each element present in a molecule of the compound, a multiple of the empirical formula.
Given that
Molar mass of compound =56.11g/mol.
The empirical formula =CH2
Molecular formula =?
We know that
It represents the actual number of atoms of each element present in a molecule of the compound, a multiple of the empirical formula.
In the given problem the CH2 follows CnH2n formula
Here n=4
Mass =56.0.
molecular mass=56.0 and n = 4, that is, C(1 × 4)H(2 × 4)
The molecular formula of the compound is given below.
C4H8 (butene or butylene)
