Agas mixture contains rn, he and n2. what is the total pressure of the mixture, if the mole fraction of n2 is 0.350 and the pressure of n2 is 0.580 atm?

We can solve this problem using Raoults law. The formula for Raoults law is:

P_a = X_a * P

where,

P_a = the partial pressure of substance A

X_a = the mole fraction of substance A

P = total pressure

Therefore calculating for P:

P = P_a / X_a

P = 0.580 atm / 0.35

P = 1.657 atm

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
