What is the partial pressure of each gas, and what is the total pressure in the flask? a. 3400000 atm (total pressure) b. 1.2 atm c. 110 atm d. 1.4 atm e. 1.1 atm f. 3400000 atm g. 0.11 atm h. 1100 atm i. 1200 atm j. 0.19 atm
A 1.00 g sample of water is introduced into a 0.767 L flask containing some O2 gas. The flask is heated to 215.93 °C at which temperature all of the water is converted to the gaseous phase, giving a total pressure in the flask of 6.010 atm. 1. Calculate PH20 (in atm) in the flask at 215.93 °C. Report your answer to three decimal places in standard notation (i.e. 1.234 atm). 交答案 Tries 0/99 2. Calculate PO2 (in atm) in...
