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.
The molar mass of a substance is the molecular weight in grams. All you need to do is calculate the molecular weight and stick the unit g/mol after the number and that is the molar mass for the substance in question. Calculate the molar mass of Al(NO. (1 x 26.98) + (3 x 14.007) + (9 x 16.00) = 213.00 g/mol. 213.00 grams is the mass of one mole of aluminum nitrate. 213.00 grams of aluminum nitrate contains 6.022 x 10 23 entities of Al(NO.
