Ammonium nitrate decomposes to form gaseous dinitrogen monoxide and liquid water. Suppose we have a flask with a movable piston in which pressure is kept constant at 1.00atm. If an 8.00gram sample of solid ammonium nitrate is introduced into the flask what is the volume of the flask in liters at 298K when the ammonium nitrate has completely decomposed?
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
