Answer:
197.07 K
Explanation:
To solve this problem we can <u>use the PV=nRT equation</u>, where:
- P = 205 kPa ⇒ 205 * 0.00986 = 2.02 atm
- V = 0.0120 m³ ⇒ 0.0120 * 1000 = 12 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
We<u> input the data</u>:
- 2.02 atm * 12 L = 1.50 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
Answer:
The correct answer is 1.778 milligrams per liter.
Explanation:
Based on the given information, the concentration of chlorine gas given is 27 pounds or 27*453.59 = 12327.93 grams.
The quantity of water given is 750000 gallons or 750000 * 3.754 = 2815500 L
The concentration of chlorine used up by the microorganism is 2.6 mg/L or 0.0026 gm/L.
Thus, for 2815500 L of water, the amount of chlorine used is,
= 2815500 * 0.0026
= 7320.3 grams
The left quantity of chlorine is 12327.93 - 7320.3 = 5007.63 grams
The concentration of residual chlorine is,
= 5007.63 g/2815500 = 0.00177859 or 1.778 mg/L.
Answer:
33.8km/h
