A cylinder of argon gas contains 50.0 L of Ar at 18.4 atm and 127 °C. How many moles of argon is in the cylinder?

n=28.03

Explanation:

For this problem you would have to use the Ideal gas law formula which is . In this formula, R is called the ideal gas law constant which is R= 0.08205

For your problem, this formula would look like this...

First you would have to convert Celsius to Kelvin:   273 + 127 C= 400K

Your problem would look like this in the formula

Once solved n= 28.03 mol

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
