how would you prepare an absportion spectrum for a purified soltion of b-carotene dissolved in acetone using the materials and e
1 answer:
Answer:
Use a series dilution
Explanation:
The rationale behind the experiment is that the different substances absorb light at different wavelengths. To prepare an absorption spectrum for a purified solution of b-carotene dissolved in acetone, firstly, the -carotene needs to be diluted enough to reach the light spec in the 20 tube. This will be done through a series of serial dilutions of a known concentration of the chlorophyll component. The bankmill will consist of acetone only and 1 blank will be needed. The range of the wavelength would be in the range of 400 - 700 nm. So, the intervals of 20 nm will suffice. Then, the OD for each wavelength will be used to determine the adsorption.

Operating Leverage = 3.00
Explanation:
<u>Income Statement :</u>
<em>Sales - Expenses = Income</em>
Note : I have separated Variable and Fixed Expenses
<u>Contribution Margin ratio :</u>
<em>Contribution Margin ratio = Contribution ÷ Sales</em>
= $1,728,000 ÷ $2,880,000
= 0.6 or 60 %
<u>Break-even sales ( units and dollars) :</u>
<em>Break-even sales (units) = Fixed Costs ÷ Contribution per unit</em>
= $1,152,000 ÷ $144.00
= 8,000
<em>Break-even sales (dollars) = Fixed Costs ÷ Contribution margin ratio</em>
= $1,152,000 ÷ 0.60
= $1,920,000
<u>Margin of safety in dollars and as a percentage of sales :</u>
<u />
<em>Margin of safety in dollars = Expected Sales (dollars) - Break-even sales (dollars)</em>
= $2,880,000 - $1,920,000
= $960,000
<em>Margin of safety in % = (Expected Sales - Break-even sales ) ÷ Expected Sales</em>
= $960,000 ÷ $2,880,000
= 33.3 %
<u>Operating leverage</u>
<em>Operating Leverage = Contribution ÷ Earnings Before Interest and Tax</em>
= $1,728,000 ÷ $576,000
= 3.00
