Question

write the molecular formula of sulphur trioxide step by step

Answer 1

Answer:

Sulfur trioxide - SO3.

Explanation:

Sulfur trioxide: SO3.

How I came to this conclusion:

I noticed that the compound consists of non-metals, therefore it must be a covalent compound - meaning I use prefixes for compounds.

Sulfur is S. Simple enough. Trioxide has the prefix of tri, meaning "3". Therefore there is 3 atoms of oxygen. Combine them and I get SO3.

Don't be confused with sulfite: (SO3)2− and sulfate: (SO4)2−

Hope this helps :)

please it's a request please mark brainlist

Answer 2

So3 is the formula and sulphur has 32u molecular mass and oxygen has 16u mloecular mass
So 32×1+16×3=32+48=80u is the answer
