A 1000 cm3 container of ammonia (NH3) has a mass of 20.7g, it is stored at room temperature (298 K). When empty the container has a mass of 20.0 g, calculate the pressure inside the container in kPa to an appropriate number of significant figures.

Using PV = nRT, make a note of the information you have, what you can calculate and what you need to find. P <-- need to find this V = 1000 cm 3 n <-- can be calculated from mass = mr X mol since we kn...
