QuestionFind the atom counts in the formula for aluminum sulfate $=\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}$.

Studdy Solution
Calculate the number of oxygen atoms.
$$\text{Number of O atoms} =4 \times3 =12$$So, in one molecule of aluminum sulfate, there are2 aluminum atoms,12 sulfur atoms, and12 oxygen atoms.
