Convert 2.39 x 1022 molecules of water into moles of water

torisob [31]

Answer:

$0.0397\ \text{mol}$

Explanation:

Number of molecules of water = $2.39\times 10^{22}$

$N_A$ = Avogadro's number = $6.022\times 10^{23}\ \text{mol}^{-1}$

Number of moles is given by

$\dfrac{2.39\times 10^{22}}{6.022\times 10^{23}}$

$=0.0397\ \text{mol}$

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