A piece of metal has a mass of 200 g and a volume of 40 cm3.
What is its specific gravity?
What is its density? g/cm3
Indicate subject in "School Subject" blank to get tutors who are experts in that area.
Since this is not my area of expertise, I searched Google under the key words "specific gravity density".
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps.
