When you say package (a sty file), I'm sure you rather mean class (see 
below). First, the document with clear distinction of v and \nu is in 
Computer Modern ---designing which Donald Knuth made sure italic v and 
\nu were not to be confused; the second document uses mathptmx for fonts 
(Times).

If you only need the facilities of achemso, you can use the package like 
this:

	\documentclass{article}% <- or any other class: book, etc.
	\usepackage{achemso}

and your document will use Computer Modern as default font.

If you really need to use the achemso class, you can resort to the 
txfonts package with the varg option. Try typesetting this example:

	\documentclass[12pt]{achemso}

	\usepackage[varg]{txfonts}

	\begin{document}

	Some text and \( v \; \nu \)

	\end{document}

the document still will use Times fonts but v and \nu will be different 
enough. See the txfonts documentation:
