Why addition of water to oxalic doesn't affect the molarity?
Adding water to a solution of oxalic acid does not affect its molarity because the total number of moles of oxalic acid in the solution remains the same. Molarity is calculated based on the number of moles of solute divided by the volume of the solution, so as long as the number of moles of oxalic acid stays constant, the molarity remains unchanged.
How can the molarity of a solution be changed?
The molarity of a solution can be changed by adding more solute to increase the concentration or by adding more solvent to decrease the concentration.
What is the molarity of the solution when 65.9 mLs of water is added to 403 mLs of 2.39 M solution of HCl?
By adding 65.9 mL of water to the 2.39 M solution of HCl, the final volume becomes 469.9 mL. To find the final molarity, we use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, and M2 and V2 are the final molarity and volume, respectively. Substituting the values, we can calculate the final molarity of the diluted solution.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
What is molarity of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
To find the molarity, we first need to convert the mass of water to volume using the density of water. Given the density of water is approximately 1000 g/L, 6 kg of water is equivalent to 6000 g or 6 L. Next, calculate the molarity using the formula Molarity (M) = moles of solute / liters of solution. In this case, 2 moles of NaOH in 6 L of water gives a molarity of 0.33 M.

What is the molarity of iron III nitrate made from 10 ml of a 1.00 M solution and then diluted by adding 90 ml of water?
The molarity is 0,1 M.
How can the molarity of a solution be changed?
The molarity of a solution can be changed by adding more solute to increase the concentration or by adding more solvent to decrease the concentration.
What is the effect on the molarity of a solution of adding more solvent to a solution?
Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
What is molarity pure water?
Pure water does not have a molarity because it is not a solute dissolved in a solvent. However, under standard conditions, the molarity of pure water is 55.56 mol/L, which corresponds to its concentration of water molecules.
Why doesn't adding water to a vinegar sample prior to titration affect the calculated molarity?
That is a question that confuses many. It is because the water is not acidic and therefore does not affect a colour change. You have a known volume of vinegar when starting the experiment.
What is the relationship between the percentage change in mass and sucrose molarity?
Change in mass depends on the concentration of sucrose within the dialysis bags. If the concentration of sucrose is greater inside the bag than outside, then water will move into the bag. If the concentration of sucrose is lower inside the bag than outside, then water will move out of the bag.

What is molarity of 720g of pure water?
The molarity of pure water is 55.56 mol/L.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
