Write each of the following as an empirical formula. If it is already an empirical formula, put a check mark. C4H1006 1) Al(SO3)1.5 CH3 Fe(NO3)3

Solution

1) Empirical formula: It is the formula giving the proportion of the elements present in the compound but not the actual numbers or arrangement of atoms.

C₄H₁₀O₆   : Empirical formula is C₂H₅O₃

Al(SO₃)_1.5 : Empirical formula is Al₂(SO₃)₃

CH₃: It is already an empirical formula.

Fe(NO₃)₃ : It is already an empirical formula.

Cr₂O₆ : Empirical formula is CrO₃
