Which of the following gives same number of ions as Al2(SO4)3
Answers
Answer:
3 x 4 oxygen, 3 x 1 sulfur and 2 aluminum in each of the 3 formula units of aluminum sulfate. So 3(17) = 51 atoms. Since Sulfate is an ion (3) of them and Aluminum forms an ion (Al 3+) of which there are 2, that would be 5 ions in each formula unit, so 3(5) = 15 ions.
