A sample of sulfur dioxide (SO2) is initially at a temperature of 105C, a volume of 15 L, and a pressure of 1.5 atm. If the volu

Agata [3.3K]

The new pressure is 1.08 atm

From the question, we are to determine the new pressure

Using the General gas equation,

$\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}$

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature

P₂ is the final pressure

V₂ is the final volume

and T₂ is the final temperature

From the given information,

P₁ = 1.5 atm

V₁ = 15 L

T₁ = 105 C = 105 + 273.15 = 378.15 K

V₂ = 25 L

T₂ = 181 C = 181 + 273.15 = 454.15 K

P₂ = ?

Putting the parameters into the equation, we get

$\frac{1.5 \times 15}{378.15} = \frac{P_{2} \times 25 }{454.15}$

$P_{2}= \frac{1.5 \times 15 \times 454.15}{25 \times 378.15}$

P₂ = 1.08 atm

Hence, the new pressure is 1.08 atm
