Purpose: To devise and implement a procedure capable of determining the identity of an unknown salt by reacting it with sulfamic acid. Observations: -Barometric pressure of Baker hall: 746 mm/hg -Unknown solid number 5313 -Mass solid + Vial = 18.22g -Mass Vial = 15.285g -Mass solid = 2.935 -Temperature of water in beaker (aka temperature of Nitrogen)= 23C -Note: we ran out of water in our Florence flask toward the end of the reaction. -Mass of water + beaker = 580.3 g - Mass beaker = 193.146 g - Mass water = 387.154 g Calculations: 387.154g water (1g/ml water) = 387.154 ml water (nitrogen produced) PV=nRT (.981579atm)(.387154L)=n(.08206)(296.15K) n=.015999 mols Nitrogen Because Nitrogen and the unknown salt are in a 1:1 ratio during the reaction, we

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
