<p>Do we need to memorize all the constants and equations? Like the density of water, Avogado's constant, etc</p>
<p>I can't remember... I don't think any constants were provided... None of the questions required any of that stuff though.</p>
<p>Dont you need to calcuate using the equations?</p>
<p>So what do you need to know? I am using barrons and a lot seem irrelevant.</p>
