Question

1) A sample of Xe gas has a volume of 852 mL, has a pressure of 523 mm Hg, and is at a temperature of 17.1 °C. Calculate the amount (in moles) of Xe in the gas sample.= ? mol

2) A sample of CCl4 with a pressure of 1.81 atm and a volume of 206 mL is allowed to react with excess CH4 at 195 °C.

Calculate the pressure of the CH2Cl2 produced in the reaction if it is transferred to a 1.61-L flask and cooled to 38

A sample of Xe gas has a volume of 852 mL, has a pressure of 523 mm Hg, and is at a temperature of 17.1 degree C . Calculate the amount (in moles) of Xe in the gas sample.= ? Mol A sample of CCl4 with a pressure of 1.81 atm and a volume of 206 mL is allowed to react with excess CH4 at 195 degree C. Calculate the pressure of the CH2Cl2 produced in the reaction if it is transferred to a 1.61-L flask and cooled to 38 degree C

Explanation / Answer

1)PV=nRT

    n=PV/RT

      =( 523/760) *( 852)/(82.1*290.1)

      =0.024moles.

2)    p1v1/T1=P2V2/T2

       1.81* 206/468=P2*1.61*1000/311

          P2=72.02 atmp

the pressure of the CH2Cl2 produced in the reaction=p2-p1=72.02-1.81=70.21 atmp
