Open Question: If the total atmospheric pressure is 760.00 mm Hg, what is the partial pressure of CO2?
Use dalton's law
Partial pressure of CO2=Molar Fraction of CO2*Total pressure
PCO2=XCO2Ptotal
Molar Fraction of CO2=moles of CO2/total moles in the gas mixture.
Substitute the values in the above equation and solve.

Open Question: A balloon is floating around outside your window. The temperatrue outside is -1 degree C and the air pressure?
use PV=nRT
n = 3.3 mol
T = -1+273.15 K
R = gas constant
P = 0.800 atm
solve for V

Open Question: Vapor Pressure of Water?
The vapor pressure of pure water at 25°C is 23.8 mm Hg. What is the vapor pressure
of water above a solution made by dissolving 18.0 g of glucose (a nonelectrolyte with a molar mass of 180.0 g/mol) in 95.0 g H2O?

Open Question: Calculating pressure of gas help?
Home >All Categories > Science & Mathematics >Engineering >Open Question
Marisa Member since:September 08, 2010Total points:156 (Level 1)In the Alka Seltzer Lab, a group doing the experiment found the pressure in the room to be 761.1 mmHg. The water was at 22.2 C. Water at this temperature has a vapor pressure of 20.070 mmHg. Calculate the pressure of the gas generated by the Alka Seltzer (CO2).Answer QuestionBe the first to answer this question.

Open Question: how to find the weight of something using hyd. pressure reading?
Pressure = Force / Area
In this case, the force = weight
Pressure = weight / Area
Area is the area of the cylinder = pi*d^2/4
Weight = Pressure * Area = Pressure * pi*d^2/4
