<p>Hey guys I'm trying to do this lab called "Determining the Molar Volume of a Gas" but I can't figure out two questions. can somebody help me with them?</p>
<ol>
<li><p>In setting up this experiment, a student noticed that a bubble of air leaked into the eudiometer tube when it was inverted in the water bath. What effect would this have on the measured volume of hydrogen gas? Would the calculated molar volume of hydrogen be too high or too low as a result of this error? Explain.</p></li>
<li><p>A student noticed that the magnesium ribbon appeared to be oxidized-the metal surface was black and dull rather than silver and shiny. What effect would this error have on the measured volume of hydrogen gas? Would the calculated molar volume of hydrgoen be too high or too low as a result of this error? Explain.</p></li>

<p>Thanks!! :):)</p>
