Chemistry

- 25.0-L tank contains 295 gN₂, 135 g O₂, and 24.0 He gases. Calculatethe partial pressure of each gas and the total gas pressure at20.0^oC.
Â Â Â Â Â Â Â Â (Answer:P_N2 = 10.1 atm; P_O2 = 4.06 atm;P_He = 5.77 atm; P_total = 19.9 atm)
- A 5.0-gallon gas tank containsN₂ and H₂ gas, such that the partial pressureof H₂ is three times that of N₂ gas. If thetotal gas pressure is 2.4 atm at 25^oC, how many grams ofN₂ and H₂, respectively, are present?(Answer: 13 g of N₂ and 2.8 g of H₂)
Thank you for your your help, if youcan help me showing me the process to learn about it at least ofone I will appreciate
