How are molarity and osmolarity different? What property of salts necessitates this distinction? How does this property affect t
lubasha [3.4K]

<u>Explanation:</u>

The number of moles that are present in a liter of a solution is called Molarity. Mole is the unit of Molarity.The concentration of the solutes that are present in a solution refers to Osmolarity . The unit is osmol. This helps in observing the movement of water from one side to another side of a semipermeable membrane.

The main property of salts that helps to understand the differentiation between the molarity and osmolarity is the salts Ionization.  One mole Na+ and one mole of Cl- is produced by the dissociation of a mole of sodium chloride occurs. The diffusion of water is the osmosis. Here, the one molar sodium chloride solution produces a osmotic pressure which is high than one molar glucose solution and this will not undergo dissociation.

Describe one chemical property of Group 1 metals that results from the atoms of each metal having only one valence electron.
sp2606 [1]
Their ability to lose that electron easily. This property is electronegativity. Once that electron is taken away, the atom becomes an ion with a charge of +1. The ion would be much more stable than the atom, because once the electron is lost, the shell underneath will already have 8 electrons that resembles the configuration of a noble gas.
