Density = Mass divided by Volume
So what you do is 80.00 ÷ 0.99755.
Which I believe would equal <span>80.1964813794
Hope this helps! </span>
The answer is: They have no freedom to move.
However is not completely true, as even in a solid atoms still a move a bit (vibrations).
If atoms were able to slide past each other, then we would have a liquid not a solid. Liquids "flow" but never really "break apart" this is because atoms are sliding between them, think of these as a bucket of marbles rolling down a slope.
If they are free to move in all directions, then you have a gas; that's why someone uses perfume in a room, eventually everyone smells it.
Answer:
The answer is 17.03052. We assume you are converting between grams Ammonia and mole.
5.5/-38 / 5.5 = 1/-6.9 x 1.3 = 1.3/-8.98
unit volume/temperature x searching amount
i’d say the temperature would be -8.98 C simply - I don’t know what formula youd use for this
<u>Answer:</u> The number of molecules of ethinyl estradiol present in one pill are 
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

Given mass of ethinyl estradiol = 0.038 mg =
(Conversion factor: 1 g = 1000 mg)
Molar mass of ethinyl estradiol ![(C_{20}H_{24}O_2)=[(20\times 12)+(24\times 1)+(2\times 16)]=296g/mol](https://tex.z-dn.net/?f=%28C_%7B20%7DH_%7B24%7DO_2%29%3D%5B%2820%5Ctimes%2012%29%2B%2824%5Ctimes%201%29%2B%282%5Ctimes%2016%29%5D%3D296g%2Fmol)
Putting values in above equation, we get:

According to mole concept:
1 mole of a compound contains
number of molecules
So,
of ethinyl estradiol will contain =
number of molecules
Hence, the number of molecules of ethinyl estradiol present in one pill are
