Question

How many moles of sf6 are there in 459500000000000000 molecules of sf6

Answer 1

Answer : The number of moles of
`SF_6` is,
`7.63* 10^(-7)` moles.

Solution :

As we know that,

1 mole contains
`6.022* 10^(23)` number of molecules

As,
`6.022* 10^(23)` number of molecules of
`SF_6` are present in 1 mole of
`SF_6`

So,
`4595* 10^(14)` number of molecules of
`SF_6` are present in
`(4595* 10^(14))/(6.022* 10^(23))=7.63* 10^(-7)` moles of
`SF_6`

Therefore, the number of moles of
`SF_6` is,
`7.63* 10^(-7)` moles.
