Four gases were combined in a gas cylinder with these partial pressures: 3.5 atm N2, 2.8 atm O2, 0.25 atm Ar, and 0.15 atm He.

What is the total pressure inside the cylinder?
6.7
atm
What is the mole fraction of N2 in the mixture?
0.52
atm

What is the total pressure inside the cylinder?

⇒ 6.7 atm

What is the mole fraction of N2 in the mixture?

⇒ 0.52 atm

What is the mole fraction of O2 in the mixture?

⇒ 0.42 atm

What is the mole fraction of Ar in the mixture?

⇒ 0.037 atm

Explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
