Chapter 7:Quantitative Composition of Compounds

The true formula, representing the total number of atoms of each element present in one molecule of a compound. A compound can have a 1:1 ratio of elements and be a different compound depending on the number of atoms present. It can be calculated from the empirical formula is the molar mass is known. Quantitative Composition of Compounds% Composition from Experimental Data q Calculate mass of compound formed q Divide mass of each element by total mass of compound and multiply by 100. Aluminum chloride is formed by reacting 13.43 g aluminum with 53.18 g chlorine. What is the % composition of the compound? 13.43 gAl + 53.18 gCl = 66.61 gAlCl3 13.43 gAl 66.61 g AlCl3 Ê Ë Á
