Oxygen is produced by the reaction of sodium peroxide and water.

2Na2O2(s) + 2H2O(l) --- O2(g) + 4NaOH(aq)

a. Calculate the mass of Na2O2 in grams needed to form 4.80g of oxygen.
b. How many grams of NaOH are produced when 4.80 g of O2 is formed?
c.When 0.48g of Na2O2 is dropped in water, how many grams of O2 are formed?
