How many molecules are in 117.0 grams of Al2(So4)3

704.574

Explanation:

There are 6.022 gram in one molecule so when you multiply 6.022 times 117.0 you come up with the answer 704.574

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the volume increases
