Answer 1

Answer:

1 mole of water = 18g

1g = 1/18 mol

16.94g = 1/18 × 16.94 == 0.94 mole

Answer 2

Given :

Mass of water = 16.94 g

To Find :

Number of moles present in 16.94g of water.

Solution :

We know, one mole of water has a mass of 18 gm.

We are required to find the moles present in 16.94g of water. So,

18 gm of water      =   1 mole of water

1 gm of water        =  $\frac{1}{18}$ mole of water

16.94 gm of water =  $\frac{1}{18}$ × 16.94 mole of water

                              = 0.94 mole

Therefore, 0.94 moles are present in 16.94 gm of water.
