Question

if % of cobalt in a complex is 0.25% by mass , minimum molecular mass of complex will be

Answer 1

Answer:

The molecule has 0.25% metal. This means the mass of metal is 0.25% of total mass of molecule. Therefore, 100% mass of molecule= 59*100/0.25=23600 u. The molecular mass of the molecule should be 23600 g.
