Answer:
A saturated solution is a mixture in which the maximum amount of a given solute has been dissolved into the solvent. ... At this point adding more solute will not change the concentration of the solution; adding more solute will simply result in more solid at the bottom of the solution.
The balanced chemical equation will tell you the molar ratios in which hydrogen and oxygen react to form water:
2H2 + O2 ----> 2H2O
Then the ratio is 2 mol of H2 react with 1 mol of O2 and form 2 mol of H2O:
2 : 1 : 2
Now convert the given data into moles:
16 grams of H2 = 16 g / 2 g/mol = 8 mol
16 grams of O2 = 16 g / 16 g/mol = 1 mol.
Then you have that the 1 mol of oxygen will react with 2 moles of hydrogen and they will form 2 mol of H2O.
And you can calculate the mass of 2 moles of H2O by multiplying by its molar weigth: 18 g/mol.
2 mol H2O * 18 g/mol = 36 grams of water.
Then, the answer is 36 grams of H2O.
