Stoichiometry (Make sure your equations are balanced) 1) According to the following balanced reaction, how many moles of KO are required to exactly react with 5.44 moles of H2O ? KO(s)+H2O(l)KOH(s)+O2(g) 2) How many grams of oxygen are formed when 6.21 moles of KOH are formed? KO(s)+H2O(l)KOH(s)+O2(g) 3) Consider the following balanced reaction. What mass (in g ) of CO2 can be formed from 288mg of O2 ? Assume that there is excess C3H7SH present. C3H7SH(l)+O2(g)CO2(g)+SO2(g)+H2O(g)
