The ratio in aluminum chloride is 1:3 aluminum to chloride ( AlCl3 or Al2Cl6 )
Count them :- Al = 1 Cl = 3 that makes 4 atoms
Al(NO3)3 > 1
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
2 Al and 3 O
Pieces of atoms? 6.01024 atoms of aluminum (1 mole Al/6.022 X 10^23) = 9.98047 X 10^-24 moles of aluminum ---------------------------------------------------
Count them :- Al = 1 Cl = 3 that makes 4 atoms
Sixteen. The formula for aluminum permanganate is Al(MnO4)3. There is one atom of aluminum (Al), three atoms of manganese (Mn), and twelve atoms of oxygen (O).
Al(NO3)3 > 1
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
Al(3+) + Cl(1-) = AlCl3
2 Al and 3 O
3.20 moles aluminum (6.022 X 1023/1 mole Al) = 1.93 X 1024 atoms of aluminum -------------------------------------------
Pieces of atoms? 6.01024 atoms of aluminum (1 mole Al/6.022 X 10^23) = 9.98047 X 10^-24 moles of aluminum ---------------------------------------------------
16. 2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum -------------------------------------------
By definition, 1 mole of anything is 6.022 x 1023 particles of that thing. So, 1 mole of Al = 6.022 x 1023 atoms Al 7.5mol Al x (6.022 x 1023 atoms Al/1mol Al)=4.5165 x 1024 atoms Al
I am not sure of the work but, i know the answer is 8.9 X 10^23 atoms Al.
Al(OH)3 One atom of aluminum. Three atoms of oxygen. Three atoms of hydrogen.
