What is the molar mass of calcium acetate?
The molar mass of calcium acetate is approximately 142 g/mol.
How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
To calculate the moles of potassium hydroxide needed, use the formula: moles = molarity * volume (in liters). First, convert 300 mL to liters (0.3 L). Then, moles = 0.250 mol/L * 0.3 L = 0.075 moles of potassium hydroxide needed to prepare the solution.
Calculate the pH of a 0.01M solution of sodium acetate?
The pH of a 0.01M solution of sodium acetate would be around 8.9. This is because sodium acetate is a salt of a weak acid (acetic acid) and a strong base (sodium hydroxide), so it produces a basic solution. The acetate ions react with water to form hydroxide ions, increasing the pH.
What is the molarity of a 1000 ml solution containing 65.12 g of potassium cyanide?
To calculate the molarity, first convert grams of potassium cyanide to moles using its molar mass. The molar mass of potassium cyanide (KCN) is about 65.12 g/mol. Next, calculate the number of moles in the solution. Finally, divide the moles by the volume of the solution in liters (1000 ml = 1 L) to find the molarity.
What is the molar mass of sodium acetate?
82.03 g/mol (anhydrous)=136.08 g/mol (trihydrate)=
How do you prepare the molar solution of K2Cr2O7?
Dissolve 294,185 g of potassium dichromate in 1L demineralized water.
How to prepare 1 molar zinc uranyl acetate solution?
Theoretically: dissolve 571,59 g of zinc uranyl acetate in 1 L water. But zinc uranyl acetate is not so soluble. I recommend a concentration of max. o,1 M (57,159 g of zinc uranyl acetate in 1 L water).
Why you can use 4.9035 g K2Cr2O7 to prepare 0.1 n solution?
To prepare a 0.1 N solution of K2Cr2O7, you need to calculate the molar mass of K2Cr2O7 and use the formula for normality. By dividing the given weight by the molar mass, you can determine the number of moles present, and then calculate the normality using the volume of the solution.
How does one prepare a 0.1M standard solution of potassium hydrogen phthalate?
To prepare a 0.1M standard solution of potassium hydrogen phthalate, you would first weigh out the appropriate amount of potassium hydrogen phthalate (KHPh) based on its molar mass, which is 204.22 g/mol. Dissolve this amount in distilled water and make up the solution to the desired volume, typically in a 1 liter volumetric flask. Finally, mix the solution thoroughly to ensure complete dissolution.
What is the molar mass of Hydrocortisone acetate?
the molar mass of cortisone acetate is about 403.2 g/mol.
How much solid potassium dichromate must be added to prepare 150 mL of 0.200 M solution of K2Cr2O7 (molar mass 294 gmol)?
To prepare a 150 mL (0.150 L) solution of 0.200 M potassium dichromate (K2Cr2O7), you can use the formula: [ \text{mass} = \text{molarity} \times \text{volume} \times \text{molar mass} ] Substituting the values, you get: [ \text{mass} = 0.200 , \text{mol/L} \times 0.150 , \text{L} \times 294 , \text{g/mol} = 8.82 , \text{g} ] Therefore, you need to add 8.82 grams of solid potassium dichromate to prepare the solution.
How I will make 3 Molar solution of potassium chloride in 250 milliliter?
To make a 3 Molar solution of potassium chloride in 250 milliliters: Calculate the mass of potassium chloride needed using its molar mass. Dissolve this mass of potassium chloride in a small amount of water, then add water to bring the total volume to 250 ml. Stir to ensure complete mixing and dissolve the potassium chloride completely.
What is the concentration of a solution that with a volume of 660 that contains 33.4 grams of aluminum acetate?
The chemical formula of aluminium acetate is Al(CH3COO)3 and the molar mass is 161,9745 g.The concentration of your solution is 50,6 g/L.
What is the molar mass of calcium acetate?
The molar mass of calcium acetate is approximately 142 g/mol.
How do you prepare 0.02 m phosphate buffer?
To prepare a 0.02 M phosphate buffer, you would need to mix suitable amounts of a monobasic potassium phosphate and a dibasic potassium phosphate solution with water to achieve the desired concentration. Calculate the required volumes of each solution based on their respective concentrations and molar masses. Finally, adjust the pH as needed with the addition of acid or base.
What mass of potassium benzoate trihydrate is needed to prepare one liter of a 0.125 molar solution of potassium benzoate?
From the definition of molar concentration, the required amount of solute for the solution specified is 0.125 moles. The gram formula mass for potassium benzoate trihydrate is 214.26. Therefore, the mass required is 0.125 X 214.26 or about 26.8 grams, to the justified number of significant digits.
