Answer
c) C₈H₁₈
Step-by-step explanation
Given that:
A compound has a molecular weight of 114.22 g/mol
The empirical formula for the compound is C₄H₉
What to find:
To determine the molecular formula for the compound.
Step-by-step solution:
(Empirica formula)n = (Molecular weight)
(C₄H₉)n = 114.22
(4 x 12.01 + 9 x 1.01)n = 114.22
(48.04 + 9.09)n = 114.22
57.13n = 114.22
Divide both sides by 57.13
n = 114.22/57.13
n = 2
Therefore, the molecular formula for the compound is (C₄H₉)₂ = C₈H₁₈
The correct answer is option c) C₈H₁₈
