Answer:
Changes in climate can result in impacts to local air quality. Atmospheric warming associated with climate change has the potential to increase ground-level ozone in many regions, which may present challenges for compliance with the ozone standards in the future.
It gives information to the brain I think I’m not entirely sure !!83
Yeah!
Answer:
The answer to your question is 2.52 moles
Explanation:
Data
Volume = 60.5 l
Temperature = 20°C
Pressure = 1 atm
Constant of ideal gases = R = 0.082 atm l/mol°K
Formula
PV = nRT
-Solve for n
n = PV / RT
-Convert temperature to °K
Temperature = 20 + 273
= 293°K
-Substitution
n = (1 x 60.5) / (0.082 x 293)
-Simplification
n = 60.5 / 24.026
-Result
n = 2.52 moles
The osmotic pressure at 65 °C of an aqueous solution containing 2.50 g of sucrose is 0.988 atm
<h3>How to determine the mole of sucrose </h3>
- Mass of sucrose = 2.5 g
- Molar mass of sucrose = 342 g/mol
- Mole of sucrose =?
Mole = mass /molar mass
Mole of sucrose = 2.5 / 342
Mole of sucrose = 0.0073 mole
<h3>How to determine the molarity of sucrose </h3>
- Mole of sucrose = 0.0073 mole
- Volume = 205 mL = 205 / 1000 = 0.205 L
Molarity =?
Molarity = mole / Volume
Molarity of sucrose = 0.0073 / 0.205
Molarity of sucrose = 0.0356 M
<h3>How to determine the osmotic pressure </h3>
- Molarity (M) = 0.0356 M
- Temperature (T) = 65 °C = 65 + 273 = 338 K
- Gas constant (R) = 0.0821 atm.L/Kmol
- Van't Hoff factor (i) = 1 (sucrose is non-electrolyte)
- Osmotic pressure (π) =?
π = iMRT
π = 1 × 0.0356 × 0.0821 × 338
π = 0.988 atm
