Answer:
2.6 atm
Explanation:
At constant temperature, solubility of gas increases as pressure increases, Hence, they varies directly proportional.
i.e S ∝ P
where:
S₁ and P₁ are the initial solubility and pressure of the gas
S₂ and P₂ are the final solubility and pressure of the gas
Making P₂ the subject of the formula from the above equation; we have:
where; it is given from the question that:
P₁ = 1.0 atm
S₁ = 0.36 g/L
S₂ = 9.5 g/L
Replacing the values into the above equation; we have:
P₂ = 2.6 atm
∴ The pressure needed to produce an aqueous solution containing 9.5 g/L of the same gas at 0°C = 2.6 atm
