A 1.41x10-1 g sample of water is introduced into a 0.825 L flask containing some C2H2 gas. The flask is heated to 178.52 C at which temperature all of the water is converted to the gaseous phase, giving a total pressure in the flask of 2.902 atm. 1. Calculate PH20 (in atm) in the flask at 178.52 C. Report your answer to three decimal places in standard notation (i.e. 1.234 atm). 6.01E-5 atm Submit Answer Incorrect. Tries 1/99 Previous Tries 2.
