Naturally occurring copper has two isotopes with relative atomic masses 62.9 3 and 64.928. if the average relative atomic mass is 63.546, what are the relati ve % abundances of the two isotopes in this sample. 2. Magnesium hydroxide, Mg(OH)2 can be commonly found in antacids. Calcula te the percentage composition, by mass, of each element in magnesium hydro xide. 3. 21.2 g sample of a compound that contained carbon, hydrogen, and oxygen w as burned in excess oxygen. The water (H20) that was produced weighed 10.8 0 g and the carbon dioxide (CO,) weighed 26.40 g. The molar mass of the com pound was determined to be 212 g/ mol. What is the molecular formula of the compound? 4.
