An empty glass container has a mass of 658.572 grams. It has a mass of 659.452 grams after it has been filled with N2 gas at a pressure of 790 torr and a temperature of 15oC. When the container is evacuated and re-filled with an unknown element (element A) at a pressure of 745 torr and a temperature of 26oC, it has a mass of 660.59 grams.
Compound B, a gaseous organic compound that consists of 85.6% carbon and 14.4% hydrogen by mass, is placed in a stainless steel vessel (10.68 L) with excess oxygen gas. The vessel is placed in a constant-temperature bath at 22oC. The pressure in the vessel is 11.98 atm.
What is the identity of element A?
2) What is the identity of compound B?
3) How many grams of C will be produced if 15.0 L of A and 12.90 L of B (each at STP) are reacted by opening a stopcock connecting the two samples?
4) What will be the total pressure in the system from a part 3?
