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? P_(T)=P_(1)+P_(2)+P_(3)+ldots +P_(n) (P_(a))/(P_(T))=(n_(a))/(n_(T)) square Iatm DONE V

To find the total pressure inside the cylinder, we can use Dalton's Law of Partial Pressures, which states that the total pressure of a gas mixture is equal to the sum of the partial pressures of the individual gases.Given:Partial pressure of N2, atmPartial pressure of O2, atmPartial pressure of Ar, atmPartial pressure of He, atmUsing Dalton's Law of Partial Pressures: atmTherefore, the total pressure inside the cylinder is 6.7 atm.
