Potassium fluoride (KF a salt has a molecular weight of 58.10 grams. How many grams would be needed to make 1.0 liter of 5.0 molar salt solution?
290 grams
How do you convert molecular weight from Dalton to grams?
To convert molecular weight from daltons to grams, you use the molar mass constant, which is 1 g/mol = 1 dalton. Therefore, the molecular weight in daltons is equivalent to the molar mass in grams per mole. Simply express the molecular weight in grams per mole.
How many Grams of Phosphate are in a 50 percent K2HPO4 Solution?
To calculate the grams of phosphate in a solution, you first need to determine the molarity of the solution. Once you know the molarity, you can use the molecular weight of phosphate to determine the grams present in the solution. Can you provide the concentration or volume of the K2HPO4 solution?
How many grams of sodium chloride are required to make a 1.0 L solution with a concentration of 3.5 M?
The molecular weight of NaCl is 58.44; sodium =22.99; Chlorine=35.45. A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L.
What is the molecular weight chlorine?
The molecular weight of chlorine is 35.453 grams per mole.
What is the molecular weight of H2?
The molecular weight of H2, which is a diatomic molecule of hydrogen, is approximately 2.01588 grams per mole.
How many grams of sodium chloride are required to make 1.0 L solution with a concentration of 3.5 m?
The molecular weight of NaCl is 58.44; sodium =22.99; Chlorine=35.45. A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L.
What weight of glucose is required to prepare 2 L of a 5 percent weight to volume solution?
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
How many grams KMnO4 take in 0.1N KMnO4 solution?
(158 g = 1 mole) --- molar mass of potassium permanganate. You also need to specify the volume to be made. For 1 liter just add 15.8 g in a volumetric flask to make 1000 ml (1 liter) of solution.
What is the molecular weight of a compound in daltons converted to grams per mole (g/mol)?
To convert the molecular weight of a compound from daltons to grams per mole (g/mol), you need to divide the molecular weight in daltons by the Avogadro constant (6.022 x 1023). This will give you the molecular weight in grams per mole (g/mol).
What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
How do you make 0.25N K2CrO4 solution?
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
