How many moles of atoms are in 50 atoms
Ba?
Answer in units of mol.
You're Welcome :)
so it would be 6.02 x 10^23 x 50? then whattt?
No.
If I multiply 6.02 x 10^23 atoms/mol x 50 atoms, I end up with some number of atoms^2/mol and you want moles. So the units aren't right so you should know that isn't the right way to do the problem. But we might think that
6.02 x 10^23 atoms/mol x mol = # atoms would be right. The only unknown in that equatin is mol. Solve for that.
thanks
To determine the number of moles of atoms in 50 atoms of Ba (barium), we need to use Avogadro's number, which is the number of atoms or molecules in one mole of a substance.
Avogadro's number is approximately 6.022 x 10^23.
To find the number of moles, we can use the following formula:
Number of moles = Number of atoms / Avogadro's number
Plugging in the values, we get:
Number of moles = 50 atoms / (6.022 x 10^23 atoms/mol)
Now let's calculate the answer:
Number of moles = 50 / (6.022 x 10^23) mol
The units cancel out, leaving us with:
Number of moles ≈ 8.31 x 10^-23 mol
Therefore, there are approximately 8.31 x 10^-23 moles of barium atoms in 50 atoms.
