Scorpion4ik [409]

Answer:

3.31 atm.

Explanation:

  • Gay-Lussac's law states that for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

∵ P α T.

<em>∴ P₁T₂ = P₂T₁.</em>

P₁ = 3.00 atm, T₁ = 20.0 °C + 273.15 = 293.15 K.

P₂ = ??? atm, T₂ = 50.0 °C + 273.15 = 323.15 K.

<em>∴ P₂ = (P₁T₂)/T₁</em> = (3.00 atm)( 323.15 K)/(293.15 K) = <em>3.307 atm ≅ 3.31 atm.</em>

KiRa [710]
The Al to Cl ratio is \frac{0.0200}{0.060} = \frac{1}{3}. Meaning that there is 1 Al to every 3 Cl, and so the empirical formula is AlCl_{3}.
