Molarity =(% by weight x density x 1000 mL/litre)/(Molecular weight x 100%)
%by weight ={(Molarity x Molecular Weight)/(density x 1000 mL/litre)} x 100%
Molecular weight - grams/mol (36.461 g/mol for HCl)
Molarity - mol/litre
Density - g/millilitre (Density may be listed as specific gravity)
For the given conditions Conc.HCl 37.0%, sp.gr. 1.19
Molarity = (37.0 x 1.19 x 1000)/(36.461 x 100)
Molarity = 12.07592 M
Available = 12.07592 M HCl
Required = 0.300 M HCl:
V1 x C1 = V2 x C2
(1000[mL] x 0.300[M]) / (12.07592[M]) = 24.84283[mL]
Dilute 24.84mL of 37.0% HCl to one liter to get 0.300M HCl solution.

use titration formula
The pH becomes lower, appoaching a level of 7 if the solution is diluted sufficiently to become almost neutral.

The terms concentrated and diluted refer to the various states of a solution. When it is concentrated, there is more solute or less solvent. In contrast, when it is diluted, there is less solute or more solvent.
This solution is diluted.
You add more solvent.
Concentrated solution. (High density solution) Supersaturated solution if amount of solute is greater than its solubility in the solvent at the given temperature.
A concentrated acid is more dangerous.
Diluted milk is milk that is diluted with water or other substance
A stock solution is a highly concentrated solution that is usually diluted in labs to get more precise moralities in experiments.
Drinking squash, concentrated vegetable boullion (stock), some fruit juices are concentrated then diluted again... basically anything that has been boiled to remove the water content is "concentrated".
exothermic
to determine the type of carbohydrate
Osmosis is a proces of transfer of a diluted solution in the zone of a more concentrated solution through a semi-permeable membrane.
Working solution is diluted to the concentration to be used in the experiment. This is opposed to the stock solution which for ease of calculation is often 10x more concentrated.
