Asked by Jessica

A 28.3 g piece of unknown metal is dropped into a graduated cylinder that has an initial volume of 14.2 mL. If the final volume of the cylinder is 16.7 mL, determine the identity of the unknown metal from its density.
Answered by Steve
the density is evidently

29.3g/(16.7-14.2)ml = 23.9/2.5 = 9.56 g/cm^3

Find that in your table of materials

Steve made two typo but othrwise the problem is ok. Just follow the steps but not the numbers. That should be 28.3g/(2.5) = ?
