When 5.467 grams of compound z are burned in excess oxygen, 15.02 grams of co2 and 2.458 grams of h2o are produced. determine its empirical formula?

Given the mass of CO2 =15.02 g

Moles of =

Mass of H2O = 2.458 g

Moles of =

Moles of C =

Moles of H =

Mass of C in the sample =

Mass of H = =0.275 gH

Mass of O in the sample = 5.467 g - (4.095 g +0.275 g) = 1.097 g O

Moles of O =

Simplest mole ratios of the elements in the compound:

Therefore the empirical formula of the compound is

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
