To find the partial pressure of nitrogen (N2) at a pressure of 10 atm, we need to know the composition of the gas mixture.
Assuming that the gas mixture contains only nitrogen and that it follows Dalton's Law of Partial Pressure, we can say that the partial pressure of nitrogen (PN2) is proportional to the total pressure (Ptotal) and the mole fraction of nitrogen (XN2):
PN2 = XN2 * Ptotal
However, we need to know the mole fraction of nitrogen in order to calculate the partial pressure.
If we assume that the mole fraction of nitrogen in air is around 0.78 (which means nitrogen makes up about 78% of the air we breathe), we can proceed with the calculation.
PN2 = 0.78 * 10 atm
= 7.8 atm
So, at a pressure of 10 atm, and assuming a mole fraction of nitrogen of approximately 0.78, the partial pressure of nitrogen would be 7.8 atm.
