Molecular weights

[amubashar]

Can some body please guide me what are the molecular weights of coal and char. The coal falls under lignite and sub-bituminous category.

Since neither coal nor char are pure substances there cannot be a well defined molecular weight.

The best you can do is to calculate a pseudo melecular weight, based on composition
(c, moisture, ash (count as silica), sulfur, ....)
But what do you want to do with that?
