The number of moles of sodium chloride in (4.2 x 10⁻⁴¹) molecules of sodium chloride is 6.973 × 10⁻⁶⁵
What are a number of moles?
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
1 mole is 6.022 × 10²³
[tex]1\; molecule = \dfrac{1}{6.023 \times 10^2^3}[/tex]
The given number of moles are 4.2 x 10⁻⁴¹
[tex]Moles = 4.2 \times 10^-^4^1 \times \dfrac{1}{6.023 \times 10^2^3} = 6.973 \times 10^{-65}[/tex]
Thus, the number of moles of sodium chloride in (4.2 x 10⁻⁴¹) molecules of sodium chloride is 6.973 × 10⁻⁶⁵
