Question

How many moles of disulfur decafluoride are present in 3.99 x 104 molecules of this compound? moles

Answer 1

Answer: The number of moles of disulfur decafluoride is
`6.62* 10^(-20)`

Step-by-step explanation:

We are given:

Number of disulfur decafluoride molecules =
`3.99* 10^4`

According to mole concept:

`6.022* 10^(23)` number of molecules are contained in 1 mole of a compound.

So,
`3.99* 10^4` number of molecules will be contained in =
`(1mol)/(6.022* 10^(23))* 3.99* 10^(4)=6.62* 10^(-20)mol` of disulfur decafluoride.

Hence, the number of moles of disulfur decafluoride is
`6.62* 10^(-20)`
