A balloon contains Helium, Neon, Argon, and Krypton gases. The pressure of the balloon is 1000 kPa. The following pressures are known: PHe = 350 kPa, PNe = 220 kPa, and PAr = 70 kPa. Determine the pressure of krypton in the balloon.

Sagot :

Answer:

360kpa

Explanation:

all those gases are noble gases.they do not react with each other.therefore the the total pressure of the balloon equals to the addition of all individual pressures of the gases.

total pressure=[ pHe+pNe+pAr+pKr]

1000kpa=[350kpa+220kpa+70kpa+pKr]

pKr=360kpa
