Answer:

This new temperature is 97.7 mL

Explanation:

Step 1: Data given

Volume = 0.225 L

STP = 1 atm and 273 K

Pressure = 2.7 atm

Temperature = 320 K

Step 2: Calculate new volume

(P1*V1)/T1 = (P2*V2)/T2

⇒with  P1 = the pressure at STP = 1 atm

⇒with V1 = the volume = 0.225 L

⇒with T1 = the temperature at STP = 273 K

⇒with P2 = the new pressure = 2.7 atm

⇒with V2 = the new volume  = TO BE DETERMINED

⇒with T2 = the new temperature = 320 K

(1atm *0.225 L)/273 K = (2.7 atm * V2) /320 K

8.24 * 10^-4 = 2.7 * V2 / 320K

2.7V2 = 0.264

V2 = 0.0977 L = 97.7 mL

This new temperature is 97.7 mL

(a) Given that Ka for acetic acid is 1.8 X 10^-5 and that for hypochlorous acid is 3.0 X 10^-8, which is the stronger acid? (b)
Gala2k [10]

Answer:

HOAc is stronger acid than HClO

ClO⁻ is stronger conjugate base than OAc⁻

Kb(OAc⁻) = 5.5 x 10⁻¹⁰

Kb(ClO⁻) = 3.3 x 10⁻⁷

Explanation:

Assume 0.10M HOAc => H⁺ + OAc⁻  with Ka = 1.8 x 10⁻⁵

=> [H⁺] = √Ka·[Acid] =√(1.8 x 10⁻⁵)(0.10) M = 1.3 x 10⁻³M H⁺

Assume 0.10M HClO => H⁺ + ClO⁻ with Ka = 3 x 10⁻⁸

=> [H⁺] = √(3 x 10⁻⁸)(0.10)M = 5.47 x 10⁻⁵M H⁺

HOAc delivers more H⁺ than HClO and is more acidic.

Kb = Kw/Ka, Kw = 1 x 10⁻¹⁴

Kb(OAc⁻) = 5.5 x 10⁻¹⁰

Kb(ClO⁻) = 3.3 x 10⁻⁷
