X₂O₃ ===> 3 moles of oxygen == > 48 g O
Molar mass of X₂O₃-------------- 48g O
30,6g --------------------------------- 14,4g
Molar mass = (30,6×48)/14,4
Molar mass = 102g
Molar mass of X₂ = 102 - 48 = 54g
Molar mass of X = 54/2 = 27g
X ==> 27 g/mol ==> Al
X₂O₃ ==> Al₂O₃

<span>The noble gases are a group of chemical elements that make up Group 18
on the periodic table. These gases all have similar properties under
standard conditions: they are all odorless, colorless, monatomic gases
with very low chemical reactivity.</span>
A persons weight changes as he travels from earth to space but his mass remains the same
Hey there!
Great question;)
Answer:it is neutrally charged because it has the same number of protons(positively charged iona) and electrons(negatively charged ions)
I hope this helps:)
