The molecular weight of elemental aluminum is 13 grams, which contains 6. 02 x 10^23 atoms. Therefore 1 gram of elemental aluminum contains [(6. 02 x 10^23) divided by 13] atoms. Notice that the value 12. 01 grams of natural carbon is the same as the atomic mass value (12. 01 amu). It also tells us that 26. 98 grams of aluminum contains exactly 6. 022 x 1023 atoms of aluminum. So 9. 0 gram of Al will contain=9/26. 998= 0. 333 moles of Al. No. Of atoms of Al in 9 gram = 0. 333× Avogadro no. =0. 333×6. 022×10^23=2. 005×10^23 atoms. This means that the mass of one mole of aluminium atoms will be 26. 982 g. As you know, one mole of any element contains exactly 6. 022⋅1023 atoms of that element. This means that if you know how many moles of aluminium you have in 4. 55 g, you can use Avogadro's number to find the number of atoms. What is the mass of 6. David G. One mole of aluminum atoms has a mass of 26. 98 grams, and contains 6. 02×1023 atoms. Dividing 26. 986. 02×1023 yields a mass of 4. 48×10−23 g for one aluminum atom.

### How do I calculate moles?

https://www.chem.tamu.edu/class/fyp/stone/tutorialnotefiles/fundamentals/empirical.htm

Start with the number of grams of each element, given in the problem. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is.

### How many atoms thick is Aluminium foil?

Each aluminum atom is about 1. 48 angstroms, so we can divide. Assuming that each aluminum atom is stacked directly on another one (which they aren't, but we can't measure without making this assumption), we come up with 1. 93 * 10^5 atoms thick.
