Asample of ar gas at 35°c occupies a volume of 1.50 l at a pressure of 3.2 atm. how many moles of the gas are present in the sample?

The moles of the gas that  are  present  in  the sample  is  0.1898 moles

   calculation

  that is PV=  nRT

 where  p (  pressure) = 3.2 atm

            V(  volume)  =  1.50 L

              n ( number of moles)  =?

               R ( gas constant)=   0.0821  atm.L/mol.K

              T(  temperature)=  35 +273 ==308  k

     n =  Pv/RT

  n  is therefore=  [3.2 atm x 1.50 L)  / ( 0.0821  atm.L/mol.K x 308 K)= 0.1898 moles
