Answer:
1.5 atm.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n is constant, and have different values of P, V and T:
<em>(P₁V₁T₂) = (P₂V₂T₁)</em>
<em></em>
P₁ = 3.65 atm, V₁ = 22.4 L, T₁ = 22°C + 273 = 295 K,
P₂ = ??? atm, V₂ = 57.4 L, T₂ = 38°C + 273 = 311 K,
- Applying in the above equation
<em>(P₁V₁T₂) = (P₂V₂T₁)</em>
<em></em>
<em>∴ P₂ = (P₁V₁T₂)/(V₂T₁) </em>= (3.65 atm)(22.4 L)(311 K)/(57.4 atm)(295 L) = <em>1.5 atm.</em>
