<u>Answer:</u> The number of moles of disulfur decafluoride is 6.62\times 10^{-20}

<u>Explanation:</u>

We are given:

Number of disulfur decafluoride molecules = 3.99\times 10^4

According to mole concept:

6.022\times 10^{23} number of molecules are contained in 1 mole of a compound.

So, 3.99\times 10^4 number of molecules will be contained in = \frac{1mol}{6.022\times 10^{23}}\times 3.99\times 10^{4}=6.62\times 10^{-20}mol of disulfur decafluoride.

Hence, the number of moles of disulfur decafluoride is 6.62\times 10^{-20}
