what is the density in kg/m3 1500 and 100.65 of nh3

To calculate the density of a substance, you need to divide its mass by its volume. In this case, we have two substances - NH3 (ammonia) with a mass of 1500 kg and another NH3 sample with a mass of 100.65 kg.

To calculate the density, you need to know the volume of each substance. If you have the volume, divide the mass by the volume to get the density. If the volume is not given, you won't be able to determine the density, as density is mass per unit volume.

Therefore, to answer your question, I need the volume of each NH3 sample in order to calculate their densities.
