# Aluminum Mass Number

The percentages of aluminum and zinc in your sample. For a sample containing a grams of aluminum and z grams of zinc: n (Hydrogen) = (a 0.0556) + (z 0.0153) (10) The number of moles of hydrogen produced per gram of sample can be calculated from: n 100%Al 0.0556 100%Zn. 0.0153 Hydrogen = b l g+b l g(11) where n. Hydrogen is the number. Available Grades include - 2011 Aluminum, 2017 Aluminum, 2024 Aluminum, 3003 Aluminum, 5052 Aluminum, 5083 Aluminum, 5086 Aluminum, 6061 Aluminum, 6063 Aluminum, 7075 Aluminum, Cast Aluminum, Mic 6 Aluminum, K100 Aluminum and more.

The largest source of aluminum in municipal solid waste (MSW) is aluminum cans and other packaging. Aluminum is also found in durable and nondurable goods, such as furniture and appliances.

This web page is a brief summary of aluminum material-specific data. For more comprehensive information, see the 2018 Data Tables on the Advancing Sustainable Materials Management: Facts and Figures Report page.

## Overview

EPA measures the generation, recycling, composting, combustion with energy recovery and landfilling of aluminum materials.

EPA used Aluminum Association industry statistics to estimate aluminum packaging generation. In 2018, aluminum generation was 1.3 percent of total MSW generation at 3.9 million tons. This included 1.9 million tons of aluminum containers and packaging, as well as two million tons found in durable and nondurable goods.

Similar to generation, EPA used industry data from the Aluminum Association to calculate recycling statistics. In 2018, the total recycling rate of aluminum containers and packaging, which includes beverage containers, food containers, foil and other aluminum packaging, was 34.9 percent. Within this number, the most recycled category of aluminum was beer and soft drink cans, at 50.4 percent (0.67 million tons).

The total amount of aluminum combusted in 2018 was roughly 0.6 million tons. This number was 1.6 percent of all MSW combusted with energy recovery in 2018.

In 2018, landfills received approximately 2.7 million tons of aluminum. This was 1.8 percent of all MSW landfilled that year.

Please see the EPA Methodology document for further information on estimating the generation and management of aluminum.

### Aluminum-31 Mass Number

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.

### Aluminum Atomic Mass Number

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
