Answer:

3.01×10²³ molecules.

Explanation:

From the question given above, the following data were obtained:

Mass of water, H₂O = 9 g

Molecules of water, H₂O =?

From Avogadro's hypothesis,

1 mole = 6.02×10²³ molecules

Next, we shall determine the mass of 1 mole of water, H₂O.

1 mole of water, H₂O = (1×2) + 16 = 18 g

Thus,

18 g of water, H₂O = 6.02×10²³ molecules

Finally, we shall determine the number of molecules in 9 g of water, H₂O. This can be obtained as follow:

18 g = 6.02×10²³ molecules

Therefore,

9 g = 9 g × 6.02×10²³ molecules / 18 g

9 g = 3.01×10²³ molecules

Thus, 9 g of water, H₂O contains 3.01×10²³ molecules.
