Being landlandlord dies not matter in chemistry in anyway..
So the answer is it doesn't matter in any way
The molecular weight of an atom is equal to the weight in grams of 1 mole of that substance. Since Be is 9.01 amu, then 1 mol of Be is 9.01 g
The chemical formula of aluminium nitrate is - Al(NO₃)₃
cation is Al³⁺
anion is NO₃⁻
One Al atom binds to three nitrate groups
the options given are
2. <span>It has three aluminum (Al) atoms
this is incorrect as there's only one Al atom
3. </span><span>It has one NO3 group.
this is incorrect as there are three nitrate groups
4. </span><span>It has nine nitrogen (N) atoms
there are only 3 N atoms therefore this too is incorrect
</span>therefore the correct answer is -
It has three NO₃<span> groups
</span>
