any idea at least?

i was thinking it wasThey both show the actual ratio of elements for a compound. @Somy

somy · Answer

Molecular formula- chemical formula that indicates the kinds of atoms and the number of each kind in a molecule of a compound. 

Empirical formula-formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.

anonymous · Answer

so Molecular formulas can be determined from empirical formulas

@iPwnBunnies what do u think? im kinda between first one and 3rd one

somy · Answer

ah no no sorry i read it wrong, 1 is wrong

somy · Answer

so yeah its 3rd one

ipwnbunnies · Answer

I don't understand choice 1. However, you can only determine the molecular formula if you know the molecular mass.

somy · Answer

then last one? im kinda confused with all these options

ipwnbunnies · Answer

I would just go with choice 3. .-.  I want to know what choice 1 means lol.

somy · Answer

lol thnx @iPwnBunnies ♥
