What mass of arsenic in grams contains the same number of atoms as 39.95 g of Argon?
The molar mass of arsenic is 74.92 g/mol, and the molar mass of argon is 39.95 g/mol. Since the same number of atoms is present in equal masses, you'd set up a ratio of their molar masses to find the mass of arsenic equivalent to 39.95 g of argon. This gives you (74.92 g/mol) / (39.95 g/mol) = 1.874. Therefore, the mass of arsenic equivalent to 39.95 g of argon is 1.874 x 39.95 g = 74.84 g.

A gas consists of a mixture of neon and argon The rms speed of the neon atoms is 350 What is the rms speed of the argon atoms?
The root-mean-square (rms) speed of a gas molecule is proportional to the square root of its temperature and inversely proportional to its molar mass. Since neon and argon gases are at the same temperature, the ratio of their rms speeds will be the square root of the ratio of their molar masses. Therefore, to find the rms speed of argon atoms, you need to calculate the square root of the ratio of the molar masses of argon to neon (molar mass of argon/molar mass of neon) and multiply it by the rms speed of neon.

Why will F2 and Ar diffuse at almost the same rate?
F2 (fluorine gas) and Ar (argon) will diffuse at almost the same rate because they have similar molar masses, which affects their diffusion rates according to Graham's law of effusion. Both gases are relatively light, and their molecular weights are close enough that the differences in their diffusion rates are minimal. Additionally, at similar temperatures and pressures, the kinetic energy of the gas molecules is comparable, leading to similar diffusion behavior.

How many argon (Ar) atoms are there in 1.5 x 102 g if argon?
To find the number of argon atoms in 1.5x10^2g of argon, we first need to determine the molar mass of argon. The molar mass of argon is approximately 39.95 g/mol. Next, we convert the given mass to moles by dividing by the molar mass. Finally, we use Avogadro's number (6.022x10^23) to convert moles to atoms. The number of argon atoms in 1.5x10^2g of argon would be approximately (1.5x10^2g / 39.95g/mol) x 6.022x10^23 atoms.
Number of argon moles in 119.98 g of argon?
The mass number of Argon is 39.948 so it is 119.98/39.948=3.0034 moles of Argon in 119.98 g of Argon or approximately 3 moles of Argon is in 119.98 g this gas.
How many moles of argon in 607 g of argon?
Have: 607gAr Need: Moles of Argon From the periodic table we know that there are 39.948gAr per every 1 mole of Argon. 607g/39.948 = your answer.
