Some oxygen gas takes up a volume of 2.00 liters at 0.99 atm and 273 K. Its volume doubles and its temperature decreases to 137

nataly862011 [7]

Answer:

The answer to your question is : letter B. 0.25 atm

Explanation:

To solve this problem we need to use the combined gas law:

T₁ T₂

Data

P1 = 0.99 atm V1 = 2 l T1 = 273K

P2 = ? V2 = 4 l T2 = 137K

Now, the clear P2 from the equation and we get

P2 = P1V1T2 / T1V2

Substitution P2 = (2 x 0.99 x 137)/(273 x 4)

P2 = 271.26 / 1092

Result P2 = 0.248 atm ≈ 0.25 atm
