how many atoms are in 10 grams of aluminum?
233743
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.

1 Expert Answer Assuming the Cl2 is in excess, this means that 8.70 moles of Al are required to make 8.70 moles Al Cl3 . However, from the periodic table, it is found that one mole of Al is 26.98 g of Al. So the required mass of Al is 8.70 x 26.98 = 234.7 g.

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
577653
For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unitis TINY.

Aluminium is located in period 3, group 13, and has an atomic number equal to 13 . This tells you that the electron configuration of a neutral aluminium atom must account for a total of 13 electrons. Now, when aluminium forms 3+ cations, Al3+ , it loses 3 electrons from its outermost energy shell.
