How many moles of atom are in 47 atoms Ba?
To find out how many moles of atoms are in 47 atoms of Ba (barium), you need to use Avogadro's number. Avogadro's number is the number of atoms or molecules in one mole of a substance, and its value is approximately 6.022 x 10^23.
The formula to calculate the number of moles is:
Number of moles = Number of particles / Avogadro's number
So, in this case, the calculation would be:
Number of moles = 47 atoms / 6.022 x 10^23 atoms/mol
Let's plug in the numbers.
