<div dir="ltr">Good evening, Dr. Pounds!

</div>
<div>I just had two quick questions about the lab: 1. How many
significant figures would you like our data to be (if it
matters)? I just noticed I had a couple of weird ones so I
took them all to four. </div>

You used the Analytical balance, which gave you five sig figs and
then you used volumetric glassware which by default it 4 sig figs.
Since you are generally doing multiplication/division work, you
should go with 4 sig figs.<br>

<div>2. For the last question on the lab, would you just
multiple (M of unknown)(0.05 L of unknown)(Molar mass of Ni)
in order to get the grams of the Ni ion?</div>

<div>Thanks!</div>
