How large a volume is need to contain 21 grams of silver? (info: density of silver is 10.5)

Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate the volume as follows:

21 grams Ag ( 1 L / 10.5 grams ) = 2 L of container is needed for the given mass of silver

Hope this answers the question. Have a nice day. 

The mass has escaped into a gas which you can not see so the law stays true.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
