AdityaDhanrajChpittu: but in most of question of vapour density there is no unit present in molecular weight

Anonymous: Vapor density is unit less

Anonymous: here 2 has a unit

Anonymous: as it the mass of Hydrogen gas

AdityaDhanrajChpittu: I know let vapour density be 10 the its molecular weight will be 20 or 20gram

Anonymous: then.......

Anonymous: g/mole

AdityaDhanrajChpittu: thanks,also can u tell me when to use relative molecular mass and molecular mass in gram

Answered by rithi3183

Whatever formula we might apply to find the molecular weight/mass the unit is

gram/mole.

Pls thank me if it really helped you. and also pls Mark as the brainliest answer.

AdityaDhanrajChpittu: Then plz tell me when to use relative molecular mass as it has no unit

rithi3183: The relative molecular mass=Mass of 1 atom of that element/Mass of 1/12 of 1 atom of C-12. As we divide mass by mass, relative molecular mass has no unit . we use relative molecular mass when we take it as a ratio with respect to 1/12 of 1 atom of C-12. hope it helps you
