(a) An ideal gas occupies a volume of 2.4 cm3 at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container. Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 10%. Double check your calculations. molecules
(b) If the pressure of the 2.4-cm3 volume is reduced to 2.2 × 10?11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container?
