Answer: The number of moles of disulfur decafluoride is [tex]6.62\times 10^{-20}[/tex]
Explanation:
We are given:
Number of disulfur decafluoride molecules = [tex]3.99\times 10^4[/tex]
According to mole concept:
[tex]6.022\times 10^{23}[/tex] number of molecules are contained in 1 mole of a compound.
So, [tex]3.99\times 10^4[/tex] number of molecules will be contained in = [tex]\frac{1mol}{6.022\times 10^{23}}\times 3.99\times 10^{4}=6.62\times 10^{-20}mol[/tex] of disulfur decafluoride.
Hence, the number of moles of disulfur decafluoride is [tex]6.62\times 10^{-20}[/tex]
