The reusable booster rockets of the U. S. space shuttle use a mixture of aluminum and ammonium perchlorate for fuel. A possible equation for this reaction is as follows. 3 Al (s) + 3 NH4ClO4 (s) → Al2O3 (s) + AlCl3 (s) + 3 NO (g) + 6 H2O (g) What mass of Al should be used in the fuel mixture for every kilogram of NH4ClO4?

0.2298kg of Al

Explanation:

From the equation of reaction

3 moles of Al (81g) is required to mix with 3 moles of NH4ClO4 (352.5g)

Mass of Al required in the fuel mixture for every kilogram (1000g) of NH4ClO4 = 1000*81/352.5 = 229.8g = 229.8/1000 = 0.2298kg
