7.996*1023 Let's see if I can remember how to do this.
I think the Atomic Mass of Argon is about 39.9 approx, so 1 mole of Argon weighs 39.9grammes.
Avogadro's number tells us how many atoms are in 1 mole of any element. The value is about 6.0221415 x 10^23.
So in 39.9grammes we have 6.0221415 x 10^23 atoms (because as far as I remember Argon is a monatomic gas - i.e. unlike for example Oxygen which hangs around in pairs of Oxygen atoms O2)
Anyway, number of atoms/particles in 23.9g of Argon would be about (23.9/39.9) x 6.0221415 x 10^23 = 3.607 x 10^23 particles.
That looks about right........................... Unless of course you meant to include sub-atomic particles................ That's too hard.
Who asked this anyway?
What else can I help you with?
How many moles of argon in 607 g of argon?

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 are in 14.5 g of argon?
To find the number of moles, divide the given mass of argon by its molar mass. The molar mass of argon is approximately 39.95 g/mol. Number of moles of argon = 14.5 g / 39.95 g/mol Number of moles of argon = 0.362 moles
How many moles of argon are in 37.9 g of argon?
To find the number of moles of argon in 37.9 g, you need to use the molar mass of argon, which is 39.95 g/mol. Divide the given mass by the molar mass to get the number of moles. So, 37.9 g / 39.95 g/mol = 0.95 moles of argon.
How many moles of argon are in 24.7 g of argon?
To find the number of moles of argon in 24.7 g, you need to divide the mass of the sample by the molar mass of argon (39.95 g/mol). Therefore, 24.7 g of argon is equal to 0.62 moles (24.7 g ÷ 39.95 g/mol = 0.62 mol).
Would you expect the particles in cl2 to diffuse faster or slower than the particles in argon gas?
Cl2 has a molar mass of about 71 g/moleArgon has molar mass of about 40 g/mole Thus, Argon will diffuse faster than Cl2 gas, or put another way, Cl2 will diffuse slower than argon.
