How many moles of water are represented by 8.33×10^18 molecules of water

number of moles of water (n) = 1.383 x10 ⁻⁵ mol

Explanation:

Data Given:

No. of molecules of water =  8.33×10¹⁸

No. of Mole of water = ?

Formula Used to calculate

no. of moles = numbers of particles (ions, molecules, atoms) /Avogadro's number

Avogadro's no. = 6.023 x10²³

So the formula could be written as

                no. of moles (n) = no. of molecules of water /6.023 x10²³

Put the values in above formula

                 no. of moles (n) = 8.33×10¹⁸ /6.023 x10²³

                  no. of moles (n) = 8.33×10¹⁸ /6.023 x10²³

                  no. of moles (n) = 1.383 x10 ⁻⁵

so  1.383 x10 ⁻⁵ moles of water are represented by  8.33×10¹⁸ molecules of water.
