There are 6.022 x 10^23 formula units per mole
2.41 x 10^24 / 6.022 x 10^23 = 4.00 moles
Answer: The number of moles of sodium chloride are 0.40 moles
Explanation:
We are given:
Number of formula units = [tex]2.4\times 10^{23}[/tex]
According to mole concept:
[tex]6.022\times 10^{23}[/tex] number of formula units are contained in 1 mole of a substance
So, [tex]2.4\times 10^{23}[/tex] number of formula units will be contained in [tex]\frac{1}{6.022\times 10^{23}}\times 2.4\times 10^{23}=0.40[/tex] moles of sodium chloride
Hence, the number of moles of sodium chloride are 0.40 moles
