Question

A sample of 0.500 moles of gas is placed in a container of volume of 2.50L. What is the pressure of the gas in ATM if the gas is at 25 degrees celcius

Answer 1

The  pressure  of  gas  at   ATm  is calculated  using  ideal  gas    equation
that  is Pv  =nRT
P  =  pressure  =?
v=  volume =  2.5  l
n= moles  =  0.500moles
T=  temperature  in  kelvin =  25 +273  =  298k
R=  gas  constant  =  0.082 l.atm/k.mol

p  is therefore =  nRT/V
p  =  (0.5  mol x0.082  l.atm/k.mol  x298k) /(  2.5l)  =  4.89  atm
