(a) An ideal gas occupies a volume of 1.8 cm3 at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container.

(b) If the pressure of the 1.8-cm3 volume is reduced to 2.4 ✕ 10−11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container?

a)pv=nRT

n=pv/RT

=(1*0.0018)/(0.0821*293)

=0.0018/24.0553

therefore,

(7.48*10^-5)*(6.022*10^23molecules/mole)=4.50*10^19molecules

Do you agree with that the formula is ,n=pv/RT?
