A gas has a solubility of 1.46 g L at 8.00 atm of pressure. What is the pressure of a sample of the same gas that
uranmaximum [27]

Answer:

14.8\ \text{atm}

Explanation:

C_1 = Initial concentration = 1.46 g/L

C_2 = Final concentration = 2.7 g/L

P_1 = Initial pressure = 8 atm

P_2 = Final pressure

From Henry's law we have the relation

\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}

The pressure of a sample of the same gas at the required concentration is 14.8\ \text{atm}.

A 17.0 L helium tank is pressurized to 22.0 atm. When connected to this tank, a balloon will inflate because the pressure inside
mel-nik [20]

Answer:

The volume of the balloon would be 374 L.

Explanation:

Initially, He occuplies a volume of 17.0 L (V₁) at a pressure of 22.0 atm (P₁). If pressure decreases to 1.00 atm (P₂), volume is expected to increase. Assuming ideal behavior of the gas and constant temperature, we can calculate the final volume (V₂) using Boyle's Law.

P_{1} \times V_{1} = P_{2} \times V_{2}\\V_{2} = \frac{P_{1} \times V_{1}}{P_{2}} =\frac{22.0atm \times 17.0L}{1.00atm} = 374 L
