Question

Convert 2.39 x 1022 molecules of water into moles of water

Answer 1

`0.0397\ \text{mol}`

Step-by-step explanation:

Number of molecules of water =
`2.39* 10^(22)`

`N_A` = Avogadro's number =
`6.022* 10^(23)\ \text{mol}^(-1)`

Number of moles is given by

`(2.39* 10^(22))/(6.022* 10^(23))`

`=0.0397\ \text{mol}`

The number of moles of water is
`0.0397\ \text{mol}`.
