1. based on the equation below, how many liters of water can be produced from 8.5 L (assume that hydrogen is in excess)

2H2(g)+O2(g) --->2H2O(g)

1 answer

When using volume only with gases, one can ignore going through the conversion to mols and just take the ratio as the volumes in the equation. You read the equation this way. 2 volumes of hydrogen react with 1 volume of oxygen. Therefore, 2.O L of oxygen at STP would react with ?? L of hydrogen at STP
