physics question about gases

Asked by student421 in Math & Science

Tags: physics maths

Some properties of ammonia (gas) at 110ºC and 101 kPa are:

viscosity, µ= 1.43 x10-5 Pa s;
heat capacity, Cp = 2.32 kJ kg-1 K-1;
thermal conductivity k = 0.039 W m-1 K-1.

Convert the above to consistent units as necessary, and calculate the ratio   µCp / k, which is known as the Prandtl number.

what consistent units must i convert. is it the KG^-1 and it should be KG?
