How do you convert 100,000 kg/hr to kmol/hr?

Answer 1

 kg/h (kilograms per hour) and kmol/h (kilomoles per hour) are not compatible.

Answer 2

You need the atomic mass of the substance being converted

Example:

NaCl atomic mass = 58.44 g/mol = 58.44kg/kmol

100,000kg/hr * 1kmol/58.44kg = 1,711kmol/hr
