<p>What are we supposed to know?</p>
<p>Something like A = abc where a is amount of a certain wavelength absorbed, a is molar absorbtivity coefficient, b is path length (in what, m?), and c is molarity of sample?</p>
<p>Halp?</p>
<p>…what??</p>
<p>i konw one of a b or c is the width of the cuvette. I seriously doubt they’ll ask this. I’m willing to bet.</p>
<p>Beer’s law- If you get drunk before the test, your AP Chem score goes down proportionally to the amount of alcohol consumed.</p>
<p>^thats what i thought at first LOL</p>
<p>although it varies depending on the rate of lightweightness</p>
<p>In fact, Beer’s Law is basically using absorbance to calculate the molecular weight and stuff. Usually used to determine an unknown compound or solution.</p>
<p>Actually, if I get drunk before the exam, I wouldn’t be surprised if my score went UP instead… That’s how badly prepared I am for this. Ugh.</p>
<p>The width of the cuvette is in cm. and is usually 1 cm. I saw this on a non-official practice test i had to do for my class and was like ***? Luckily, we were allowed to use our books… (Though we had slightly under 90 minutes so they only help so much…)</p>
