Just like you should respond to a request for an interview within 24 hours, if your contact follows up with you (good sign!), be sure to reply within one day (and ideally within a few hours).
Aluminum has a density of 2.7 grams per milliliter. An element in the boron group, aluminum is a very light metal, but it is dense enough to sink in water. It is the third most abundant element in the Earthâs crust and is the most abundant metal overall.
By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses. The density of brass is approximately .303 lb/cubic inch, 8400 to 8730 kilograms per cubic metre(equivalent to 8.4 to 8.73 grams per cubic centimetre).
