How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare a 6N ammonium hydroxide solution from a 30% solution, you would first calculate the molarity of the 30% solution. Then, you would dilute the 30% solution with water to reach the desired concentration. Calculate the volume of the 30% solution needed and dilute it with water to reach the final volume for a 6N concentration.
How many mg of Magnesium will reqiured to prepare 60ml of 20 percent solution?
To calculate the mass of magnesium needed, use the formula: mass of solute = volume of solution (ml) x percentage concentration / 100. In this case, it would be 60 ml x 20% = 12 g or 12,000 mg of magnesium will be required to prepare 60 ml of a 20% solution.
How many grams of calcium chloride would you add to water for a totoal volume of 500 ml to make a 5 percent solution?
To make a 5% solution of calcium chloride with a total volume of 500 ml, you would need to add 25 grams of calcium chloride. This is calculated by multiplying the volume of the solution (500 ml) by the desired concentration (5%) and converting to grams.
A chemist has one solution that is 80 percent acid and another solution that is 30 percent acid How much of the first 80 percent solution is needed to make a 400 L solution that is 62 percent acid?
To create a 400 L solution that is 62% acid, you would need 200 L of the 80% acid solution and 200 L of the 30% acid solution. This would result in a final solution with the desired concentration.
Calculate the mass of solid needed to make the solution 100 ml of solution that is 1.0 M in sodium cation using sodium chloride?
To make a 1.0 M solution of sodium cation using sodium chloride, you need to consider the molar mass of sodium chloride (58.44 g/mol). Since 1 mole of sodium chloride provides 1 mole of sodium cation, you would need 58.44 g of sodium chloride to make a 1.0 M solution in 100 ml.
How do you prepare 4N potassium chloride?
To prepare 4N potassium chloride solution, dissolve 149.5 g of potassium chloride in 1 liter of water. This will give you a solution with a concentration of 4N. Make sure to use a balance to accurately measure the amount of potassium chloride needed.
How many ml are needed to prepare 1 liter of 2.5 percent dextrose solution?
25
How to prepare 250ml of a 2m solution of potassium chloride?
To prepare 250ml of a 2M potassium chloride solution, measure out 17.8g of potassium chloride and dissolve it in water to make a total volume of 250ml. Make sure to stir the solution well to ensure the potassium chloride is completely dissolved. Then, adjust the final volume to exactly 250ml by adding more water if needed.
How much of a 30 percent sodium chloride stock solution is needed to make 10 ml of a normal saline solution?
The volume is 0,3 mL.
How many mL of a 20 percent solution are needed to prepare 500 mL of a 5 percent solution?
125 ml 500(ml) * 0.05 = 25 25 / 0.20 = 125
How do you prepare 10mM ferric chloride solution?
To prepare a 10mM ferric chloride solution, first calculate the molecular weight of FeCl3 to determine the amount needed to achieve a concentration of 10mM. Dissolve this amount in a known volume of water or solvent to make up the final volume of the solution, ensuring thorough mixing to achieve homogeneity.
How to prepare 1000 ppm chloride solution from sodium chloride?
To prepare a 1000 ppm chloride solution from sodium chloride, first calculate the mass of sodium chloride needed using the formula: (ppm concentration * volume of solution in liters) / 1000. Then dissolve this calculated mass of sodium chloride in the desired volume of water to make the solution. Finally, ensure the solution is thoroughly mixed before testing the concentration with appropriate methods.
How many moles of sodium chloride are needed to prepare 500 mL of a 0.250 M solution?
500ml = 500cm3 = 0.5dm3 0.250M = 0.250mol/dm3 number of moles = molarity x volume number of moles = 0.250mol/dm3 x 0.5dm3 = 0.125mol 0.125mol of NaCl is needed to prepare the required 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.
How many ml of 50 percent dextrose solution and how many ml of water are needed to prepare 4.5 L of a 1 percent solution?
90 ml of dextrose and 4.41 litres of water.
Lab preparation of neutral ferric chloride solution from solid ferric chloride?
To prepare a neutral ferric chloride solution from solid ferric chloride, first dissolve the solid ferric chloride in distilled water to form a concentrated solution. Then, slowly add a base such as sodium hydroxide solution while monitoring the pH using a pH meter until the desired neutral pH is reached. Finally, dilute the solution to the desired concentration with more distilled water if needed.
How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare a 6N ammonium hydroxide solution from a 30% solution, you would first calculate the molarity of the 30% solution. Then, you would dilute the 30% solution with water to reach the desired concentration. Calculate the volume of the 30% solution needed and dilute it with water to reach the final volume for a 6N concentration.
