Explanation The given compound is Co(NO 3 ) 2 .6H 2 O . Molar mass of cobalt is 58.9332 g/mol . Molar mass of nitrogen is 14 .0067 g/mol . Molar mass of hydrogen is 1 .0079 g/mol . Molar mass of oxygen is 15 .9994 g/mol . Molar mass of the compound Co(NO 3 ) 2 .6H 2 O is: (58 .9332 g/mol Co) + (2 × 14 .0067 g/mol N) + (12 × 1 .0079 g/mol H) + (12×15 .9994 g/mol O ) = 291.0678 g/mol . % element = mass of element/mol comp mass of comp/mol comp × 100% . Mass percent of cobalt = 58.9332 g Co 291.0678 g compound × 100% = 20
