How do you decide which of a group of solutions has the greatest concentration of hydroxide ions OH-?
Determine the concentration of hydroxide ions by looking at the molarity of the base in the solution. A higher molarity of the base will result in a greater concentration of hydroxide ions. Use stoichiometry to calculate the concentration of hydroxide ions based on the balanced chemical equation for the reaction.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
What is the chemical formula for cobalt(II) hydroxide when it reacts with water to form a solution with a molarity of 0.63 M?
The chemical formula for cobalt(II) hydroxide when it reacts with water to form a solution with a molarity of 0.63 M is Co(OH)2.
What is the molarity of a solution of sodium hydroxide if it contains 0.5 moles in 75mL of solution?
Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.
A volume of 40.0g of aqueous potassium hydroxide was titrated against a standard solution of sulfuric acid. What was the molarity of the solution if 25.7g of 1.50M was needed?
The molarity of the potassium hydroxide solution is 3.30M. This can be calculated by determining the number of moles of sulfuric acid used (0.0171 mol), then equating this to twice the number of moles of potassium hydroxide used (0.00855 mol), and finally dividing this by the volume of the potassium hydroxide solution (0.00258 L).

What is the molarity of 2.0 L sodium hydroxide solution containing 10.0 grams solute?
The molarity is 0,125 M.
How are concentrations in solutions quantified?
through molarity,molality, normality. through molarity,molality, normality.
What is the 1 molarity of Na-OH?
Molarity:1.0 mol (NaOH) /L(solution) = 1.0 M NaOHThe conversions of molality, b, to and from the molarity , c,for one-solute solutions are:c = ρ.b / [1 + b.M]andb = c / [ρ -c.M]where ρ is the mass density of the solution, b is the molality, and M is the molar mass of the solute.
What is the normality of 28 ammonium hydroxide?
To calculate the normality of ammonium hydroxide (NH4OH), we need to know the molarity first. Once we have the molarity, we can determine the normality for NH4OH by accounting for the number of equivalents it can provide in a reaction. Normality is calculated as the molarity multiplied by the number of equivalents per molecule.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
Barium hydroxide contained 2.74g in 100cm of water titration of 20cm required 18.7cm of a hydrochloric acid solution for complete neutralization what is the molarity of the barium hydroxide?
To find the molarity of the barium hydroxide solution, first calculate the number of moles of hydrochloric acid used in the titration. Then use the stoichiometry of the reaction to determine the number of moles of barium hydroxide present. Finally, divide the moles of barium hydroxide by the volume of the solution in liters to get the molarity.
What is the chemical formula for cobalt(II) hydroxide when it reacts with water to form a solution with a molarity of 0.63 M?
The chemical formula for cobalt(II) hydroxide when it reacts with water to form a solution with a molarity of 0.63 M is Co(OH)2.
What is the molarity of 5.60 mol of sodium carbonate in 1500-mL of solution?
Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ...
What is the molarity of a 2.0 L sodium hydroxide solution containing 10.0 grams of a solute?
.13 (Plato)
How does a scientist make two solutions with same molarity?
By dissolving the same number of moles of each substance in the same volume of water
What is the molarity of a solution of sodium hydroxide if it contains 0.5 moles in 75mL of solution?
Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.
