A metal block has a mass of 5 grams and a volume of 1 cubic centimeter.A piece of the same kind of metal with a volume of 2 cubic centimeters has a density of
A)2)5 g/cc.
B)5 g/cc.
C)10 g/cc.

Density is defined as mass per unit volume. From the given information, we know that the mass of the metal block is 5 grams and its volume is 1 cubic centimeter. Therefore, its density can be calculated as:

Density = Mass/Volume = 5g/1cc = 5 g/cc

Now, for the piece of metal with a volume of 2 cubic centimeters, we are not given its mass but we know that it is made of the same kind of metal as the first block. Therefore, its density should also be the same, i.e. 5 g/cc. We can calculate its mass as follows:

Mass = Density x Volume = 5g/cc x 2cc = 10 grams

So the piece of metal with a volume of 2 cubic centimeters has a mass of 10 grams and a density of 5 g/cc.

A Metal Block Has a Mass of 5 Grams and a Volume
