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

Solutions

Expert Solution

PARTIAL PRESSURE OF NITROGEN = TOTAL PRESSURE * MOLE FRACTION OF N2

= 3.9*0.25

= 0.98 BAR
