A gaseous mixture of and contains 35.8 nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 565 ?
See above.

To find the partial pressure of oxygen in the mixture, we first need to determine the mole fraction of oxygen in the mixture. The mole fraction is the ratio of the number of moles of oxygen to the total number of moles in the mixture.
Let's assume the molar mass of nitrogen is M_N and the molar mass of oxygen is M_O.
To find the mole fraction of nitrogen, we can use the given mass percent composition of nitrogen. The mass percent is the mass of nitrogen divided by the total mass of the mixture, multiplied by 100.
mass percent of nitrogen = 35.8%
To calculate the mass of nitrogen, we need to know the total mass of the mixture. However, this information is not provided in the question. Without the total mass, we cannot find the mass of nitrogen or the mole fraction accurately. Therefore, we are unable to calculate the partial pressure of oxygen in the mixture.
If you have any additional information or if the total mass is provided, we can continue with the calculation.
