<p>Can somebody help me with a few of my lab questions please? (The lab is called Determination of the Molar Mass of Volatile Liquids)</p>
<ol>
<li><p>Volatile liquids with lower boiling points often give better results than those with higher boiling points. Suggest a reason for this.</p></li>
<li><p>What effect would vapor condensation in the neck of the 15 mL Beral-type pipets have on the reported molar mass? How large an error might this introduce?</p></li>
<li><p>Some liquids have enough attractions between molecules to form dimers. (Dimers are molecules formed from the combination of identical molecules, A + A yields A2.) What effect would this have on the experimental molar mass? </p></li>
</ol>
<p>thanks! I appreciate your help!</p>
