gas sample is made entirely of carbon dioxide and water, and there are 259 moles of co2 and 513 moles of water. if the total pressure of the sample is 21 atm, what is the partial pressure of each gas?

Respuesta :

Partial pressure of CO2 ,  p'=7.0455 atm and Partial pressure of water p ''=13.9545 atm

No. of moles of CO2  , n' = 259 moles

No. of moles of water , n'' =  513 moles

Total no. of moles , n = 513+259

                                = 772 moles

Mole fraction of CO2  , X' = n' / n

                                = 0.3355

Mole fraction of water , X'' = n'' / n

                                        = 0.6645

Partial pressure of CO2 , p' = X' * total pressure

                                         = 0.3355 * 21

                                         = 7.0455 atm

Partial pressure of water , p '' = X'' * total pressure

                                            = 0.6645 * 21

                                             = 13.9545 atm

The force perpendicularly applied to an object's surface divided by the area over which it is dispersed is known as pressure. The pressure as compared to the surrounding air pressure is known as gauge pressure. To express pressure, a variety of units are employed. The tension or pressure that is applied uniformly across a confined fluid is known as hydrostatic pressure (liquid or gas). In a fluid at rest, there is no other tension conceivable. Look at the Pascal's principle. In the Earth's crust, there is a pressure called lithostatic pressure that is similar to hydrostatic pressure in fluids. It is the stress that surrounding rocks place on a body of rock.
