As pV= nRT
P = pressure
V= volume
n= number of moles
R = Universal gas constant
T = temperature
So the volume and temperature of two flasks are same. And also R is constant itslef.
So pressure is directly proportional to number of moles.
So He is having more pressure than Na so moles of He are more.
And as number of atoms = moles × avagadro number
Hence as He is having more moles .
So atoms of He gas are more than Na

Two tubes of gas are identical and are open only at one end. One tube contains neon (Ne) and the other krypton (Kr). Both are monatomic gases, have the same temperature, and may be assumed to be ideal gases. The fundamental frequency of the tube containing neon is 485 Hz. What is the fundamental frequency of the tube containing krypton? The atomic masses are given by 20.180 u for neon, and 83.80 u for krypton

Equal molar amounts of neon were collected over water in two
identical 6.0-L flasks, one being at 30 degrees Celcius and the
other being at 20 degrees Celcius, respectively. The difference of
respective total pressures in two flasks was 845.8 torr. Use the
provided table of vapor pressure versus temperature (picture) to
calculate the number of moles of neon collected in each flask.

A researcher wishes to use two identical containers (i.e. having the same volume), one to store 5 moles of O2 gas, and one to store 3 moles of N2 gas. Both are kept at 300 K and 5 atm. Is this possible? O Yes, since O2 and N2 have different molar masses. O Yes, since these conditions are not at STP. O Yes, since gases can be compressed. O No, because number of moles and temperature are directly proportional. No,...
