Question

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

Answer 1

Answer : The number of moles of $SF_6$ is, $7.63\times 10^{-7}$ moles.

Solution :

As we know that,

1 mole contains $6.022\times 10^{23}$ number of molecules

As, $6.022\times 10^{23}$ number of molecules of $SF_6$ are present in 1 mole of $SF_6$

So, $4595\times 10^{14}$ number of molecules of $SF_6$ are present in $\frac{4595\times 10^{14}}{6.022\times 10^{23}}=7.63\times 10^{-7}$ moles of $SF_6$

Therefore, the number of moles of $SF_6$ is, $7.63\times 10^{-7}$ moles.
