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

The element magnesium, Mg, has three common isotopes:24Mg, 25Mg, and 26Mg. The difference between these three isotopes is Questi

The difference between all three Magnesium, Mg isotopes is in; the number of neutrons.

<h3>What is isotopy?</h3>

Isotopy is a property of elements in which case the element has two or more types of atoms that have the same atomic number and hence, same position in the periodic table, but differ in nucleon numbers due to different numbers of neutrons in their nuclei.

Ultimately, the distinctive feature between the three isotopes is in their number of neutrons
