Question

what is the molecular formula of a compound with the empirical formula CF2 and a molar mass of 200 g/mol.

Answer 1

Explanation:

Mass of C = 12,

Mass of F = 19,

Molecular formula = n ( empirical formula )

200g = n ( 50)

therefore,

n = 4

therefore, the formula must be 4 (CF2) = C4F8
