Potassium oxide reacts with water to produce of potassium hydroxide. Please provide a balanced equation, and determine how much potassium oxide is needed to produce 80.5g of potassium hydroxide?

Answer 1

K2O + HOH ==> 2KOH
mols KOH needed = grams/molar mass = ?
mols K2O = (1/2)*mols KOH from the coefficients in the balanced equation.
grams K2O needed = mols K2O x molar mass K2O = ?
