It is known that 28 g of a certain ideal gas occupy 26.4 liters at standard conditions (0° C, 1 atm). The volume occupied by 42 g of this gas at standard conditions (in liters) is: a. 22.4 b. 14.9 c. 33.4 d. more data are needed e. 39.6

1.  The internal energy for a monatomic gas is equal to its total translational kinetic energy. 2 moles of Helium (monatomic gas, atomic mass = 4 u) are placed in a .1 m3 container and are at 60 kPa.a. Find the total translational kinetic energy?

a) An ideal gas occupies a volume of 1.6 cm3 at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container.    molecules (b) If the pressure of the 1.6 cm3 volume is reduced to 1.2 ✕ 10-11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container?  mol       example of question 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.   6.01e+19 molecules
