Answer 1

Answer #1

1) 1 atm = 760 mmhg

Pressure(P) = 632 mmhg *( 1 atm / 760 mmhg) = 0.83 atm

2) Ideal gas equation, PV = nRT

Under contant T,V conditions, Pressure(P) is directly proportional to no of moles(n).

No of mole of O2(n1) = 5/32 = 0.156 mole

No of mole of He (n2) = 5/4 = 1.25 mole

So that, He chamber having greater Pressure.

3) STP = standard temperature,pressure

Temperature = 273.15 k , Pressure = 1 atm
