you are analyzing an unknown organic compound in the lab. the sample of unknown organic compound has a mass of 18.8 grams. you decide to determine the emprirical formula of the unknown compound using combustion analysis. after combustion, you find that 27.6 grams of carbon dioxide and 11.3 grams of waer have been produced. what is the empirical formula for the unknown organic compound?

Your boss has instructed you to make up a medium for growing Gram-negative procaryotes. She wants you to be able to grow 100 mg/l of volatile suspended solids. You looked up some papers on the microorganisms and found that the empirical chemical formula for them is C5H7O2NP0.1 are minimum concentrations of NH4+-N and PO4-P that you must add to the medium?

How is the sound different when both tuning forks C AND C prime as opposed to a signal tuning are ringing?
Why the measured beat minimum amplitude is not zero try to create empirical formulas for A_beat_max=f (Ac, Ac’) and A_beat_min=f (Ac, Ac’):
List the frequencies found for the tuning forks and how do these frequencies compare to the frequencies of the notes given in lecture?

Suppose 130 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean
82g and standard deviation
1g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 79
g and 85g.
In: Math
1. Explain what it means for the normal distribution to be symmetrical about the mean?
2. Why is it important to know the mean and standard deviation for a data set when applying the empirical rule?
3. If we are focused on 68% of the normal distribution, what percentage of the distribution is left in the upper tail only?
4. What value separates the 50% of the distribution from the other 50% of the distribution?
