Question

how can we convert kj/mol into kj/kg

Answer 1

Dear Student

Mole is the unit of "amount of substance".
Kg is the unit of Mass. Although, we do use it as measure of weight (on earth).

1 mol = 6.023 x 10²³ number of atoms/ ions/ molecules etc. depending on the nature of substance.
So, there is no direct formula for such a conversion.

Calculate weight (in Kg) by Molecular/ atomic/ ionic weight.
Wt. = MW x no. of moles.

Then calculate KJ/Kg from KJ/mol
