Answer:
2.17 gm Al
Explanation:
First, find the number of moles . Then multiply by the mole weight of aluminum.
# moles = 4.85 x 10^22 / 6.022 x 10^23 = .08053 moles
.0805 moles * 26.981 gm/mole = 2.173 gm
Xenon, because the amount of protons=the atomic number, and Xenon’s atomic number is 54. Some elements with similar chemical properties would be Neon, Helium, Argon, Krypton, Nitrogen, etc because they are all in the period #18, which means they have similar properties. They are all noble gases. Hope this helps :)
