multiple choice Q
A mixture of N2, O2, and Ar has mole fractions of 0.25, 0.65, and 0.10, respectively. What is the pressure of N2 if the total pressure of the mixture is 3.9 bar?
0.67 bar |
1.33 bar |
0.98 bar |
0.39 bar |
2.5 bar |
PARTIAL PRESSURE OF NITROGEN = TOTAL PRESSURE * MOLE FRACTION OF N2
= 3.9*0.25
= 0.98 BAR
