Answer:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Explanation:
An orbital is the most probable location of an electron. This is because you can't pinpoint the exact location of an electron because as soon as you do it will have moved again, so orbitals are used to find the probability of where a certain electron is.
Answer:
![198.01~mg~of ~theobromine](https://tex.z-dn.net/?f=198.01~mg~of%20~theobromine)
Explanation:
For this case we have to go through molecules to moles, from moles to grams and finally from grams to mg. The ratios that we have to take into account are:
-) <u>1 mol = 6.023x10^23 molecules</u>
-) The molar mass of
<u>180.16 g = 1 mol</u>
-) <u>1 g= 1000 mg</u>
With this in mind we can do the calculation:
![6.62x10^2^0~molecules\frac{1~mol}{6.023x10^2^3~molecules}\frac{180.16~g}{1~mol}\frac{1000~mg}{1~g}=198.01~mg~of ~theobromine](https://tex.z-dn.net/?f=6.62x10%5E2%5E0~molecules%5Cfrac%7B1~mol%7D%7B6.023x10%5E2%5E3~molecules%7D%5Cfrac%7B180.16~g%7D%7B1~mol%7D%5Cfrac%7B1000~mg%7D%7B1~g%7D%3D198.01~mg~of%20~theobromine)
