How many atoms of each element are present in Al2(SO4)3
Answered by admin @
Answer:
In this case, Al2 means 2 aluminums, (SO4)3 means 3 (SO4)s. The parentheses mean that the 3 has to be multiplied by whatever number of atoms you have of each element inside: 3x1 sulfurs, 3x4 oxygens. Now for the grand tally: 2 aluminum atoms + 3 sulfur atoms + 12 oxygen atoms = 17 atoms total in each molecule.
