A sample of nitrogen gas was collected via water displacement. Since the nitrogen was collected via water displacement, the sample is saturated with water vapor. If the total pressure of the mixture at 21 °C is 1.16 atm, what is the partial pressure of nitrogen? The vapor pressure of water at 21 °C is 18.7 mmHg.
I set up an equation according to Dalton's Law of partial pressure ---> 1.16= P1+18.7
I keep getting the answer wrong and need help.
