A rigid cylinder with a movable piston contains a sample of hydrogen gas.
330 K this sample has a pressure of 150 K PA and a volume of 3.50 L. What is the volume of the sample at STP

Respuesta :

Answer:

The volume of gas at STP is 4.3 L.

Explanation:  

*initial temperature of gas = 330 K

*Initial pressure = 150 Kpa  (150/101.325 = 1.4804 atm)

*Initial volume = 3.5 L

*New pressure = 1 atm

*New temperature = 273.15 K

*To Find: New volume

*Formula

P₁V₁ / T₁   = P₂V₂ /T₂

*Solution:

*V₂ =  P₁V₁. T₂  / T₁ .  P₂

*V₂ =  1.4804 atm. 3.5 L . 273.15 K / 330 K . 1 atm

*V₂ =  1415.3 L / 330

*V₂ = 4.3 L

Therefore, The volume of gas at STP is 4.3 L.
