Answer 1

$\boxed{\begin{array}{c|c|c|c}\boxed{\bf Element}&\boxed{\bf No\:of\:moles}&\boxed{\bf Sample\:ratio}&\boxed{\bf Simplest\:ratio}\\ \sf C&\sf \dfrac{40.68}{12}=3.39&\sf \dfrac{3.39}{3.39}=1 &\sf 1 \\ \sf H&\sf \dfrac{5.08}{1}=5.08&\sf \dfrac{5.08}{3.39}=1.49 &\sf 1\\ \sf O&\sf \dfrac{54.24}{16}=3.39 &\sf\dfrac{3.39}{3.39}=1&\sf 1\end{array}}$
