Answer:
1.6mole of H2O
Explanation:
First let us generate a balanced equation for the reaction. This is illustrated below:
2H2 + O2 —> 2H2O
Molar Mass of O2 = 2 x 16 = 32g/mol.
Mass of O2 = 25.6g
Number of mole of O2 = Mass /Molar Mass
Number of mole of O2 = 25.6/32
Number of mole O2 = 0.8mol
From the equation,
1mole of O2 produced 2moles H2O.
Therefore, 0.8mol of O2 will produce = 0.8 x 2 = 1.6mole of H2O
