(a) An ideal gas occupies a volume of 3.0 cm3 at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container.
(b) If the pressure of the 3.0-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?
