A compound with the empirical formula CH2 was found to have a molar mass of approximately 84 g. What is the molecular formula of the compound?

C₆H₁₂

Explanation:

Given molecular weight = 84 g/mole

Empirical Formula => CH₂

Empirical Formula Wt = 12 + 2(1) = 14 g/emp formula

Molecular Multiple = Molecular Wt / Emp Formula Wt = 84/14 = 6

∴ Molecular Formula => (CH₂)₆ => C₂H₆

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
