Answer:

To find the number of moles of H2O produced, we need to use the given mass of H2O and the molar mass of water.

First, let's calculate the molar mass of water (H2O):

- Hydrogen (H) has a molar mass of approximately 1 g/mol.

- Oxygen (O) has a molar mass of approximately 16 g/mol.

So, the molar mass of water (H2O) is:

2(1 g/mol of hydrogen) + 16 g/mol of oxygen = 18 g/mol

Next, we can calculate the number of moles of H2O produced:

- Mass of H2O = 3.198 g

- Molar mass of H2O = 18 g/mol

Number of moles of H2O = Mass of H2O / Molar mass of H2O

= 3.198 g / 18 g/mol

≈ 0.1777 mol

Therefore, approximately 0.1777 moles of H2O are produced.
