There is no compound with the formula Al2Cl3. But AlCl3 is aluminum chloride.
No compound exists with this formula. However, CaCl2 (with a lowercase L) is calcium chloride, which is an ionic compound.
No such compound exists. Perhaps what is mean is Al2(CO3)3 which is aluminum carbonate.
I don't think this compound actually exists.

An ionic compound always exists in solid state.
methanol (CH4O)
a compound in an ore
The mass depends on how much you use but the molecular mass would be 160.31gmol as it is Al2Cl3.

I doubt that the stated compound exists, but if it does an acceptable name for it would be "trisulfur monobromide".
If this compound exists, it would be named "sulfur heptachloride".
