Question

You need 110 mol of water to fill his water bottle every day. how many moles of Hydrogen and Oxygen does he need to react to make 2 L of water?
*Use the equation - 2H2 + 02 --> 2H20
Steps please. Thanks :)

Answer 1

It's a good thing that water weights 18 g/g-mole.
Thus, 2 liters of water by volume is 110 g-mole.
From the equation, we use 110 g-mole of H2 and 55 g-mole of O2. That's all doc!
