Another conversion that can be made with the unit moles involves substances in the gaseous state. Substances that are a gas at S. T.P. (standard temperature and pressure---which is the only kind we will deal with for now) will have a volume of 22.4L for every 1 mole.

This means that if I have a certain number of moles of gas, then I can determine the volume of that gas. Or if I have a certain number of Liters of the gas, than I can determine the number moles.

Answer the following two questions, handwriting your work, and upload a picture of that work, with your answers boxed.

1) How many moles of Hydrogen gas are present in a sample of 37.6 L?

2) How many liters of Oxygen gas are present in a sample of 0.36 moles?

Bonus: How many molecules of Oxygen would be present in the sample from question #2?

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
