A mixture contains 2.48 g of KClO3 and an unknown mass of NaN3. When heated the following reactions take place.
2NaN3(s) → 2Na(s) + 3N2(g)
2KClO3(s) → 2KCl(s) + 3O2(g)
When the mixture is heated, it produces 1675 mL of gas at a total pressure of 1.78 atm at 95ºC.
How many g of NaN3 were in the mixture?
