My MWE is:
\documentclass{minimal}
\RequirePackage[paperwidth=70mm, paperheight=20mm, left=10pt, top=20pt]{geometry}%
\RequirePackage{fontspec}
\setmainfont[Ligatures=TeX, Numbers=OldStyle]{Tex Gyre Pagella}%
%\setmainfont[Ligatures=TeX]{Tex Gyre Pagella}%
\usepackage{mhchem}
\begin{document}
Chemical formula: \ce{Al2O3}
\end{document}
which produces
but the desired output is (and as far as I am concerned should be)
