Solve word problems involving calculations that apply the Law of Definite Composition and Law of Multiple Proportions. 1.) There is a total of 100g of Aluminum oxide (Al2O3) in a beaker. How much Aluminum in grams is in the 100g of Aluminum oxide? 2.) The mass of oxygen that combines with 1g of nitrogen to form 2 different compounds are 2.28g and 0.570g, respectively. Show how these data illustrate the Law of Multiple proportions by calculating the simplest whole number ratio.
