A compound consists of 75% magnesium and 25% oxygen. Find the empirical formula.
laila [671]
<h2>Answer:</h2>

% Composition of elements:

  • Magnesium = 75%
  • Oxygen = 25%

Atomic mass of given elements:

  • Magnesium = 24 g
  • Oxygen = 16 g

Now, divide % composition by Atomic mass:

\footnotesize\implies Mg = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{75}{24}  =  \bf 3.125

\footnotesize\implies O = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{25}{16}  =  \bf 1.5625

Simplest Ratio:

\footnotesize\implies Mg  =  \dfrac{3.125}{1.5625}  = 2

\footnotesize\implies O  =  \dfrac{1.5625}{1.5625} = 1

Empirical Formula:

\footnotesize\implies \underline{ \boxed{ \red{ \bf Empirical \:  Formula = Mg_2O}}}
