the number of moles in 4.61*10^17 atoms of radon
To find the number of moles in 4.61*10^17 atoms of radon, we need to use Avogadro's number, which is 6.022 x 10^23 mol^-1.
First, we need to convert the number of atoms to moles by dividing by Avogadro's number:
4.61 x 10^17 atoms / (6.022 x 10^23 atoms/mol) = 7.667 x 10^-7 mol
Therefore, there are approximately 7.667 x 10^-7 moles in 4.61*10^17 atoms of radon.
To calculate the number of moles in a given number of atoms, you need to use Avogadro's number. Avogadro's number is defined as 6.022 × 10^23, which is the number of atoms or molecules in one mole of substance.
To find the number of moles in 4.61 × 10^17 atoms of radon, follow these steps:
Step 1: Determine Avogadro's number:
Avogadro's number = 6.022 × 10^23
Step 2: Convert the given number of atoms into moles:
Number of moles = (Number of atoms) / (Avogadro's number)
Substituting values:
Number of moles = 4.61 × 10^17 / 6.022 × 10^23
Step 3: Simplify the expression:
Number of moles = (4.61 / 6.022) × (10^17 / 10^23)
Step 4: Calculate the result:
Number of moles = 0.765 × 10^(-6)
Therefore, the number of moles in 4.61 × 10^17 atoms of radon is approximately 0.765 × 10^(-6).
