Semi-molar refers to a solution that is halfway between being molar (having a concentration of 1 mole of solute per liter of solution) and being dilute. It typically refers to a solution where the concentration falls between 0.1 to 1 mole per liter.
Haemocyanins are a group of proteins.
It is not true, they are not identical.
The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
They're actually exactly the same in that neither of them exists.
A solution whose strength is 0.5 M
Semi-molar refers to a solution that is halfway between being molar (having a concentration of 1 mole of solute per liter of solution) and being dilute. It typically refers to a solution where the concentration falls between 0.1 to 1 mole per liter.
the pH would be 5 and the strength would be 1 X 10-5 molar
Haemocyanins are a group of proteins.
6N HCl refers to a 6 molar solution of hydrochloric acid. The strength of the acid solution is determined by its concentration. It is a moderately strong acid that can cause skin irritation and burns upon contact.
To make a 0.1 molar solution from a 1.0 molar solution, you would dilute the original solution by a factor of 10. For example, you could mix 1 part of the 1.0 molar solution with 9 parts of solvent (like water) to achieve a final concentration of 0.1 molar.
It is not true, they are not identical.
Only a compound has a molar mass not a solution.
Dissolve 29,22 g NaCl p.a. in 1 L demineralized water at 20 0C, in a volumetric flask.
The relationship between molality and molar mass in a solution is that molality is directly proportional to molar mass. This means that as the molar mass of a solute increases, the molality of the solution also increases.
The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
This solution contain 29,22 g NaCl in 1 L water solution.
