2H2(g) + O2(g) ==> 2H2O(l)
10 moles H2 will combine with 5 moles of O2 to produce 10 moles liquid water. All of that comes from the equation. How many grams will 10 moles water be? One mole is 18.015 g; therefore, 10 moles must be 180.15 g. If the density of the liquid water is 1.00 g/mL and mass = volume x density, the volume of the water will be ?? mL.
