cobalt(II) bromide: CoBr2
molar mass Co = 58.933 g/mol
molar mass Br = 79.904 g/mol
molar mass CoBr2 = (58.933 g/mol x 1) + (79.904 g/mol x 2)
molar mass CoBr2 = 218.741 g/mol
Mass percent of Co:
total mass Co = 58.933 g/mol x 1
total mass Co = 58.933 g/mol
%Co = 26.94%
Calculate the mass percent composition of each constituent element of cobalt(II) bromide.
