The density of cobalt metal is 4.51 g/cm[SUP]3[/SUP]. Calculate the volume (in cm[SUP]3[/SUP]) of a piece of cobalt weighing 8.32 g. I know the answer but am not sure how many significant figures it would be. 1.84? or 1.8? haha it confuses me! like i know its 4.51g/1.??mL. ? being the amount of zeros.
