Molar concentration is the number of moles of a substance per litre.
One litre of pure water is 1kg, or 1,000 grams.
The molecular mass of water is approximately 18 grams per mole.
Therefore, there are 1,000/18 = 55.56 mole of water in a litre of water, giving a concentration of 55.56 M.

∙ 13y agoThe molar concentration of water is 55.56 mol/L because water has a molar mass of 18.015 g/mol, and the density of water is 1 g/mL, which corresponds to a concentration of 55.56 mol/L. This means that in 1 liter of water, there are 55.56 moles of water molecules.
To find the molar concentration of a chemical compound, you need to divide the number of moles of the compound by the volume of the solution in liters. This calculation gives you the concentration in moles per liter (M). The formula is: Molar concentration (M) = moles of solute / volume of solution (in liters).
The molar concentration of nitric acid can vary depending on the specific solution. However, a common concentration of nitric acid used in laboratories is around 16 M (molar). This means there are 16 moles of nitric acid in 1 liter of solution.
To make a molar solution from a 32% hydrochloric acid solution, you would need to first calculate the molarity of the 32% solution. Molarity is calculated by multiplying the percent concentration by the density of the solution and dividing by the molar mass of the solute. Once you determine the molarity, you can then dilute the solution to the desired molar concentration by adding the appropriate amount of solvent (usually water).
Since CH3OH does not ionize in solution, the total molar concentration of ions in a 1.240 M solution of CH3OH would be 0, as there are no ions present.
To calculate the molar concentration of arsenic in a water sample with 1 ppm (parts per million) arsenic, you need to know the molar mass of arsenic. Arsenic has a molar mass of approximately 74.92 g/mol. Since 1 ppm is equivalent to 1 mg/L in water, you can convert this to moles per liter by dividing by the molar mass to find the molar concentration.
The concentration of water in pure water is 100%, meaning that all the molecules present in the solution are water molecules.
It is not true, they are not identical.
To find the molar concentration of a chemical compound, you need to divide the number of moles of the compound by the volume of the solution in liters. This calculation gives you the concentration in moles per liter (M). The formula is: Molar concentration (M) = moles of solute / volume of solution (in liters).
Not necessarily or even usually. The term "one molar" refers to the concentration of the acid added and does not have anything to do with the concentration of ferrous ions.
Example: 0,5 molar concentration of sodium chlorideThe molar mass of NaCl is 58,44 g; so 0,5 molar is 29,22 g/L
The 0.4 molar solution has a higher water potential because as the concentration of solute decreases, water potential increases. Water potential is a measure of the tendency of water to move from one area to another, and it is affected by factors like solute concentration and pressure.
The molar concentration of nitric acid can vary depending on the specific solution. However, a common concentration of nitric acid used in laboratories is around 16 M (molar). This means there are 16 moles of nitric acid in 1 liter of solution.
Solution a with a concentration of 0.25 molar has the lowest concentration of NaCl among the given options.
3998 + 5556 = 9554
Molar absorptivity is independent of concentration in moles per liter. It is a constant that depends on the specific solute and solvent, and reflects how well a compound absorbs light at a specific wavelength. The molar absorptivity remains constant regardless of the concentration of the solute.
To make a molar solution from a 32% hydrochloric acid solution, you would need to first calculate the molarity of the 32% solution. Molarity is calculated by multiplying the percent concentration by the density of the solution and dividing by the molar mass of the solute.
