Explanation / Answer

The reaction is as follows:

2 H2 + O2 ------> 2H2O

Mass of O2 = 4.65 g

Molecular weight of O2 = 32 g/mol

Moles of O2 = 4.65 g / 32 = 0.1453 mol

1 mol O2 produces 2 moles of water from reaction

Here we have 0.1453 moles, so it produces 0.2906 moles

Mass of water produced

= molar mass * moles

= 18 g/mol * 0.2906

= 5.23 g

Thus, mass of water produced = 5.23 g
