What metal has a mass of 158g and a volume of 20mL?

What your tutor wants here is to find out is if, from the information given, you can determine the nature of the metal.Which you should be able to do. You should first determine the specific gravity, the weight in grams per cubic centimetre.And then explore the metals you know of to find one with similar density.158 / 20 = 7.9 g/cc. (Or since there are 1000 000 cc in a m3, multiply by 1 000 000.) which gives us 7.9000 tonnes/cubic metre.In a list of density of the elements, iron comes in at 7.87 tonnes per m3.Which for the present purposes looks a good candidate.
