    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.

    I believe significant figures would be 2 after the decimal. They both have two so you can be accurate to 2. If one only had one then you could only be accurate to 1.
