Take a hypothetical sample of exactly 100 grams of the solution.
(16g urea) / (60.06 g urea/mol) = 0.2664 mol urea
((100 g total) - (16g urea)) = 84.0 g H2O = 0.0840 kg H2O
(0.2664 mol) /0.0840 (kg) = 3.17143mol/kg = 3.18m urea
Non-volatile mixtures can be separated using a process called thin layer chromatography (TLC). Since acetaminophen has a hydroxyl group, it is more polar than phenacetin.
<h3>Does acetaminophen or phenacetin have a lower Rf value?</h3>
Since acetaminophen has a hydroxyl group, it is more polar than phenacetin. Phenacetin will be more soluble and migrate to the top than the polar component because we are employing a non-polar solvent.
Non-volatile mixtures can be separated using a process called thin layer chromatography. The experiment is carried out on a piece of glass, plastic, or aluminum foil that has been lightly covered with an adsorbent substance. Typically, silica gel, cellulose, or aluminum oxide are utilized as the substance.
Because acetaminophen is more polar than phenacetin and nonpolar molecules pass through silica gel more quickly than polar ones do, acetaminophen would have a lower Rf value.

Answer:
You need to do the following conversion to pass from 3M in 250 mL to g of sodium acetate
Explanation:
First, you need to dissolve 61.52 g of solid sodium acetate (MW 82.03 g/mol) in 200 ml of DI water. Then, using a volumetric flask add water to bring the total volume of the solution to 250 mL.
Answer:
Cl2 does not have any charge
Explanation:
But when it is present in its ionic form then chlorine have -1 charge on it. But charge on chlorine varies from -1 to +7
