The Stoichiometry of molar concentration follows this simple formula:
Mol = Volume (dm³) × Molar Concentration (mol/dm³)
Hence: Molar Concentration (mol/dm³) = Number of moles (mol)/ Volume (dm³)

∙ 12y agoBy applying the formula:
No. of moles = Mass of compound / Molar Mass of compound
eg:
We have to find concentration of KMnO4,so ;
No.of moles of KMno4 = Mass of KMnO4 / Molar mass of KMnO4

How are you able to find the concentration of a chemical in water?
The concenrtation is determined using the chemical analysis of the solute concentration; methods as densimetry, refractometry can sometimes by used.
To find the molar mass of a chemical do you add up all of the atomic masses of the elements in the chemical?
Yes- for example: H2SO4 The molar mass for hydrogen is 1.008 g/mol, for sulfur is 32.07 g/mol, and that of oxygen is 16.00 g/mol. Note that these values may vary slightly depending on the periodic table that you use. To find the molar mass: (2 x 1.008) + 32.07 + (4 x 16.00) = 98.09 g/mol
What is a list of scientific compounds?
There are thousands of chemical compounds. One chemical can form many different compounds depending on what is is combined with, and new combinations can also be formed. Thus, a list of ALL of them would be unlikely to contain all chemical compounds.
How find percent compsotion of oxygen in Na2O?
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
What is lithium's molar mass?
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
How do you find the molar mass of compounds like water?
The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a periodic table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses. H: 2 x 1.00794g/mol = 2.01588g/mol O: 1 x 15.9994g/mol = 15.9994g/mol ------------------------------------------------ Molar mass = 18.0153g/mol
What is the molar concentration of 80 g of glucose dissolved in sufficient water to make 2 L of a solution?
The equation to find molar concentration is C= n/v (concentration= moles/volume). For 80g of glucose, you would first need to find the number of moles; n= m x mm (moles= mass x molar mass). Then you can input that number into the equation C= n/v.

How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
How do you find triammonium citrate concentration in aqueous solution?
A chemical determinatiom of the ion citrate is necessary.
What is molar mass in chemistry?
Complex Answer: Molar mass is the sum of the masses of all the atoms in a compound. Molar mass, is a physical property characteristic of a given substance (chemical element or chemical compound), namely its mass per mole of substance as grams per mole (g/mol or g mol−1), especially in chemistry. A mole is another unit of measurement. It is the quantity of anything that has the same number of atoms found in 12 grams of carbon-12. That number is Avogadro's Number, which is usually stated as 6.022 x 1023.Simple Answer: It is the amount of a substance in moles.

What is the molar mass of HCl?
The molar (molecular) mass of hydrochloric acid is found by adding up the atomic masses of both elements in the compound. (appx.)H= 1.0Cl= 35.5HCl= 36.5 grams
