3.85 atoms Al (1 mole atoms Al/6.022 X 10^23)
= 6.39 X 10^-24 moles aluminum
( though 3.85 atoms seems unlikely )
9.55 mol of Al
Pieces of atoms? 6.01024 atoms of aluminum (1 mole Al/6.022 X 10^23) = 9.98047 X 10^-24 moles of aluminum ---------------------------------------------------
you should multiply by 6.022x10^23 to go from moles to atoms/molecules/particles
Sounds like an acid metal reaction to produce hydrogen gas, so I will assume you meant hydrochloric acid. Complete reaction indicates aluminum is limiting and drives the reaction. 2Al + 6HCl --> 2AlCl3 + 3H2 3.0 moles Al (3 moles H2/2 moles Al) = 4.5 mole hydrogen gas produced =========================
1 mole of atoms = 6.022 x 1023 atoms 6.2mol x 6.022 x 1023 atoms/mol = 3.7 x 1024 atoms Al
5.75x10^24 atoms x 1 mole/6.02x10^23 atoms = 9.55 moles of Al

1 mole Al = 6.022 x 1023 atoms Al 0.2mol Al x 6.022 x 1023 atoms Al/1mol Al = 1 x 1023 atoms Al (rounded to 1 significant figure)
A mole is 6.022x1022. Therefore, 5.75x1024/6.022x1022 = 95.482323 moles (9.55 moles of Al).________________________________________________________________Source: e2020
