Suppose you’re in the business of making fresh water from salt water and you are using electricity to do so. If you are given 5 Liters of Hydrogen and 4 Liters of oxygen, find the limiting reactant in the equation above, show your work below. (HINT: at STP 1 mole of gas = 22.4 Liters, determine moles of each at STP first.)

thomaster · Answer

The equation is  $\Large\sf 2H_2+O_2\to 2H_2O$

You have 5 liters of hydrogen and 4 liters of oxygen.
First find the amount of moles hydrogen and oxygen you have by using the hint.
22.4 liter gas = 1 mol
