Given 4.8 moles of a gas in a 1.8 l container, if the temperature is found to be 31 degrees celsius, what is the pressure of the gas? (the ideal gas constant is 0.0821 l · atm/mol · k and 1 atm = 760 torr.)
6.79 torr
66.55 torr
6.79 x 100 atm
6.66 x 101 atm

Answer : The pressure of the gas is,

Solution :

Using ideal gas equation,

where,

n = number of moles of gas  = 4.8 moles

P = pressure of the gas = ?

T = temperature of the gas =

R = gas constant = 0.0821 Latm/moleK

V = volume of gas = 1.8 L

Now put all the given values in the above equation, we get the pressure of the gas.

Therefore, the pressure of the gas is,

i'm pretty sure its b i might be wrong though!

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.
