Answer:
17.47 atm
Explanation:
We need to do some conversions of units to determine this answer
Mixture of gases: He, N₂ Ar
Total pressure: 22.1 atm
Sum of partial pressures of each gas from the mixture = Total pressure
Partial pressure He + Partial pressure N₂ + Partial pressure Ar = 22.1 atm
Partial pressure N₂ = 22.1 atm - Partial pressure He - Partial pressure Ar
We convert partial pressures Ar and He to atm
2475 Torr . 1atm / 760 Torr = 3.25 atm → Partial pressure He
1049 mmHg . 1 atm / 760 mmHg = 1.38 atm → Partial pressure Ar
We replace data:
Partial Pressure N₂ = 22.1 atm - 3.25 atm - 1.38 atm → 17.47 atm
Answer:
It's 5 mark as brainliest answer
The potassium chloride is KCl. The gram formula mass of KCl is 39+35.5=74.5 g/mol which means 74.5 g per mole of KCl. So the mass of KCl is 6.90*74.5=514 g.
