What is the molarity of sodium borate?
The molarity of sodium borate (Na2B4O7) would depend on the concentration of the solution. To calculate molarity, you would need to know the amount of sodium borate dissolved in a known volume of solvent. Molarity is expressed in moles of solute per liter of solution.
How do you determine pH of sodium carbonate?
Having the Molarity, concentration, helps. Molarity = moles of solute ( gotten from the grams put into solution ) divided by Liters of solution. Then. - log( Molarity of compound ) = pH ====( if basic subtract from 14 )
What is the molarity of 0.2 Normal sodium bicarbonate solution?
Since Normality (N) is a measure of the number of equivalents of a substance in a solution, and molarity is a measure of the concentration of a substance in a solution, to convert from Normality to Molarity for sodium bicarbonate (NaHCO3), you would need to divide the Normality by the total acidity or basicity of the compound. Since sodium bicarbonate has one replaceable hydrogen atom (H), the molarity is equal to the Normality for this compound. Thus, the molarity of a 0.2 Normal sodium bicarbonate solution is 0.2 M.
What would need to be recorded to calculate the concentration of the acetic acid solution?
To calculate the concentration of the acetic acid solution, you would need to record the volume of acetic acid used, the total volume of the solution, and the molarity of the sodium hydroxide solution used during the titration.
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.

Is normality and molarity for sodium thiosulfate same?
No, normality and molarity are not the same for sodium thiosulfate. Molarity is a measure of the concentration of a solution based on the number of moles of solute per liter of solution, while normality is a measure of the concentration of a solution based on the equivalent weight of the solute. The normality of sodium thiosulfate will depend on the number of equivalents of the solute present in the solution.

How can you calculate the concentration of a phosphoric acid solution from the titration with sodium hydroxide?
You can calculate the concentration of a phosphoric acid solution by determining the volume of sodium hydroxide needed to neutralize it in a titration. The molarity of the sodium hydroxide solution and the balanced chemical equation for the reaction will allow you to find the moles of phosphoric acid present, hence the concentration.
What is the molarity of NaCl concentration of blood?
The molarity of NaCl in blood is typically around 0.9%, which is equivalent to approximately 0.154 M. This concentration is close to the physiological concentration of sodium chloride in the body and is often used in medical settings as isotonic solution.
What would need to be recorded to calculate the concentration of the acetic acid solution?
To calculate the concentration of the acetic acid solution, you would need to record the volume of acetic acid used, the total volume of the solution, and the molarity of the sodium hydroxide solution used during the titration.

Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
What is the molarity of Na plus ions in a 0.25 M solution of Na3PO4?
The molarity of Na+ ions in a 0.25 M solution of Na3PO4 is 0.75 M. This is because each formula unit of Na3PO4 dissociates into 3 Na+ ions in solution. Therefore, the concentration of Na+ ions is three times the molarity of the Na3PO4 solution.
Why is standardization of sodium chloride solution with the help of known silver nitrate solution needed?
Sodium chloride may be used as standard (for example to prepare sodium solutions with known concentration) because is a stable compound.
What is the molarity of a 0.75 L solution that contains 9.1 g sodium chloride?
This molarity is 0,207 mol.
What is the difference between molarity and moles per liter of solvent?
Molarity has to deal with the concentration of solute in a concentration, and Moles per liter of the solvent is the concentration of solvent.
