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

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
