Acompound with a molar mass of 100.0 g/lol has an elemental composition of 24.0% c, 3.0% h, 16.0% o and 57.0%f. what is the molecular formula of the compound?

If I made no mistake in calculation, the given answer must be correct...(tried my best)

elements   :                        carbon     hydrogen    oxygen       Fluorine

 composition [C]                     24             3                16                57

M r                                          12             1                16                19

(divide C by Mr)                       2               3                 1                  3

(Divide by smallest value)       2                3                  1                  3

(smallest value = 1...so all value remained constant)

Empirical formula : C2H3OF3

if molar mas = 100 g per mole, then

first step calculate Mr. of empirical formula:  [= 100]

Them molecular formula = empirical formula

    

Six base units were recommended: the metre, kilogram,second, ampere, degree kelvin (later renamed kelvin), and candela. in 1960, the 11th  cgpm  named the system the international system of units, abbreviated si from the french name, le système international  d'unités.
