Answer to Problem 10R

The mole of water is 6.9 moles.

Explanation of Solution

Given:

The mass of water is 125 g.

Formula used:

Number of moles can be expressed as

  numberofmoles=massofH2OmolarmassofH2O.... (1)

Calculation:

Molar mass of moles is 18 g/mole.

  numberofmoles=125g18g/mole=6.9mole

Conclusion:

Hence, the mole of water is 6.9 moles.
