The question is either incomlete or it doesn´t make sense. Are you looking for the atomic mass, density or somethig else.\nAs it is, the best answer to your question would be: "depends on how much aluminum".

Well, look in the periodic table of the elements and find the molecular weight. The molecular weight tells you how many grams are in one mole of that element. Once you know the amount of grams that correspond to 1 mole, you do the math.\nGood luck!

Ataomic weight or number of Neutrons.  The number of protons determine what element it is, and how many neutrons determines it's weight and what isotope it is.

The atomic number of an element is equal to the number of protons the element has in the nucleus of one atom.\nThe number of protons in the nucleus determine what element it is.\n\nThe atomic mass of an element is equal to the sum of number of protons and the number of neutrons in the nucleus.  The electrons around the atom are neglected since their mass is negligible, as well as the fact that atoms can form ions by gaining and/or loosing electrons even though the element is the same.

There's no way to tell - it depends on the density of the material tht you're talking about. 900 cubic feet of lead is much heavier than 900 cubic feet of water.

Look up the atomic mass (sometimes called atomic weight) on the periodic table, and subtract the atomic number from it.  The atomic mass is (practically) equal to the total number of protons and neutrons, and the atomic number is equal to the number of protons.  When you subtract atomic number from atomic mass your subtracting the number of protons from the total number of protons and neutrons, which leaves you with just neutrons.

The atomic mass of a chemical element is the mass of an atom at rest, most often expressed in unified atomic mass units. The atomic mass is often synonymous with relative atomic mass, average atomic mass and atomic weight; however, it is subtly different in that it can either be the abundance-weighted average of isotope masses of an element or the mass of a single isotope.\n\nThe relative atomic mass (also known as atomic weight and average atomic mass) is the average of the atomic masses of all the chemical element's isotopes as found in a particular environment, weighted by isotopic abundance. Periodic tables usually list these with reference to the local environment of Earth's crust and atmosphere. An uncertainty in parenthesis is often included. For artificial elements the nucleon count of the most stable isotope is listed in brackets as the atomic mass

I would assume that lead pellets would be heavier than aluminum. Try placing them in a liquid which is buoyant for aluminum and the lead should fall to the bottom. Thick Veg Oil or something? A magnet might work too. Not sure though.

Ok, let's set this straight. Weight is a measure of the force exerted on an object by a gravitational field. It is measured in NEWTONS. Most people are getting this mixed up with mass, which can be measured in metric tons and doesn't change from one gravitational field to another. The weight of the lead on the moon is only 166 Newtons.

The atomic # of the element is the # of protons and (some times electrons) in the element
