<h2>Periodic Table toobox</h2>

<p>Nothing to see here, this toolbox is running in the console. Try for example:</p>
<p>
<pre> Na + Cl</pre>
<pre> > 58.439769282 </pre>
<pre> H*2 + O</pre>
<pre> > 18.015 </pre>
<pre> C*6 + H*12 + O*6</pre>
<pre> > 180.156 </pre>
<pre> H*2 + S + O*4</pre>
<pre> > 98.072 </pre>
</p>
<hr>
<p>You can also try it with molecules, using the periodic table's eval method:</p>
<pre> pt.eval('H2SO4')</pre>
<pre> > 98.072 </pre>
<p>pt.eval will also recognize multiplier prefixes as one will often find in reaction formulas with </p>
<pre> pt.eval('2H2SO4')</pre>
<pre> > 196.144 </pre>
<pre> pt.eval('C9H8O4')</pre>
<pre> > 180.159 </pre>
<pre> pt.eval('pt.eval('CH3COOC6H4COOH')')</pre>
<pre> > 180.159 </pre>
<pre> pt.eval('pt.eval('CH3COOC6H4COOH')')</pre>
<pre> > 180.159 </pre>
<pre> pt.eval('Ca(OH)2')</pre>
<pre> > 74.0924 </pre>
