the number of moles in 4.61*10^7 atoms of radon
To find the number of moles, we need to use Avogadro's number:
1 mole = 6.022 × 10²³ particles
So, first we need to convert the given number of atoms to moles:
4.61 × 10⁷ atoms × 1 mole/6.022 × 10²³ atoms = 7.666 × 10⁻¹⁶ moles
Therefore, there are approximately 7.666 × 10⁻¹⁶ moles in 4.61 × 10⁷ atoms of radon.
To calculate the number of moles in a given number of atoms, you can use Avogadro's number (6.022 x 10^23).
First, convert the given number of atoms to moles using the following equation:
Number of moles = Number of atoms / Avogadro's number
Let's calculate the number of moles in 4.61 x 10^7 atoms of radon:
Number of moles = (4.61 x 10^7 atoms) / (6.022 x 10^23 atoms/mol)
Number of moles ≈ 7.6483 x 10^-17 moles
