1) 1.00 x 10
26
atoms of an
ideal gas are placed in a
container whose volume
can be changed.
a) How many moles of gas are in the container?
b) What is the temperature of the gas?
c) If the gas is composed of neon (atomic mass
m
= 3.35 x 10
26
kg) what is the average
speed of the neon atoms?
Initially the gas has a volume of 3.00 m
