Calculate the moles of CaO reacted and use the balanced equation to find the mass of H2O reacted. Subtract this mass of water initially to find the excess water
Since all the necessary molar masses are already provided, construct a dimensional analysis to find the mass of H2O reacted
Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide:
CaO(s) + H2O(l) → Ca(OH)2(s)
A 5.00-g sample of CaO (molar mass = 56.077 g/mol) is reacted with 4.83 g of H2O (molar mass = 18.02 g/mol). How many grams of water (the reactant in excess) remain after the reaction is complete?
