The answer is A Krypton and xenon have complete electron clouds.
1 mole Cs ------------ 6.02x10²³ atoms Cs
1.2 moles Cs ------------- ?
1.2 * 6.02x10²³
= 7.224x10²³ atoms
hope this helps!

Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
Explanation:
All the points that are given below are true to have been affecting the war theory positively. The untimely and unnatural death that were happening earlier was prevented after introduction of germ theory and keeping a check on the germs that were inflicting death.
Also the accidental discovery of X-Ray helped the soldiers to get an overview of what was happening inside the body. The nuclear power plants help generate atomic energy and brought in the concept of nuclear weapons so did happen with atoms as well which lead to development atom bombs that were very useful in wars
