Answer: -
The concentration is 0.91 mol/ L
Explanation: -
The osmotic pressure = 23 atm
Absolute temperature = 309 K
Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹
We know the formula
Osmotic pressure = molar concentration x universal gas constant x absolute temperature
Plugging in the values
23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K
Molar concentration = 
mol/ L
= 0.91 mol / L
Answer:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
Ethene (H2C=CH2) is a gaseous by-product of the long-chain hydrocarbons that are cracked to create highly sought-after goods like gasoline and aviation fuels.
<h3>What is ethene used for?</h3>
- The uses of ethene include: It is employed in the creation of polythene. It is used to make fruits artificially ripe.
- Ethene is also utilised to create other beneficial molecules such ethanol, oxyethylene flame, and ethylene glycol, which is used as an antifreeze.
<h3>Does ethylene resemble ethene?</h3>
- A substance having the chemical formula C2H4 is ethylene, commonly known as ethene.
- It is both the most easily manufactured organic compound in the world and the simplest alkene.
- Unsaturated hydrocarbon ethylene, often known as C2H4, is utilised in industrial facilities and is occasionally found in typical medicine cabinets as a hormone.
