This solution should contain 0.500 grams anhydrous cobalt(II)-sulfate (CoSO4) per litre.
When using mono- or heptahydrate, increase the weighted mass by the relevant molar mass ratio.
Molar masses:
154.996 g/mol CoSO4 (anhydrous)
173.01 g/mol CoSO4.H2O (monohydrate) ==> ratio 173/155 = 1.12, so 0.556 g/L
281.103 g/mol CoSO4.7H2O (heptahydrate) ==> ratio 281/155 = 1.81, so 0.905 g/L
To dilute 1000 ppm to 500 ppm, you need to add an equal amount of the solution without any concentration. For example, if you have 1 mL of the 1000 ppm solution, you would need to add 1 mL of water to make it 500 ppm.
Let x be the amount of the 20% solution and y be the amount of the 65% solution. The total volume equation is: x + y = 500. The total amount of the solute equation is: 0.20x + 0.65y = 0.45(500). Solve these two equations to find the amounts of each solution needed.
Amikacin sulfate injection is used to treat serious bacterial infections, such as certain types of pneumonia, septicemia, and skin or soft tissue infections. It belongs to a class of antibiotics called aminoglycosides, which work by disrupting bacterial protein synthesis. It is usually reserved for infections caused by bacteria resistant to other antibiotics or for patients who cannot tolerate other antibiotics.
To calculate the mass of medication in the solution, multiply the volume of the solution (500 ml) by the concentration of the medication (10%). Convert the percentage to a decimal by dividing by 100 (10% = 0.10). So, 500 ml x 0.10 = 50 grams of medication in 500 ml of a 10% solution.
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
To make a 500 ml solution of 3% H2O2 from a 50% solution, you would need to dilute the 50% solution with water. You would add 325 ml of water to 175 ml of the 50% H2O2 solution to achieve a final volume of 500 ml with a concentration of 3% H2O2.
To dilute 1000 ppm to 500 ppm, you need to add an equal amount of the solution without any concentration. For example, if you have 1 mL of the 1000 ppm solution, you would need to add 1 mL of water to make it 500 ppm.

To make a 20% dextrose solution, you need to dilute the 70% dextrose solution with water. You need to use 178.57 ml of the 70% dextrose and 321.43 ml of water to make 500 ml of 20% dextrose solution.
Take 5 grams of calcium chloride and dissolve it in 100ml of solution to get a 5% solution of calcium chloride. The standard way to make a weight-volume solution is to take grams of the dry substance in 100ml of volume.
Let's say the total solution is 100 liters. 50 of the liters is glucose and 50 is water. We want to make the 50 glucose equal to 10% of the total solution. For that to happen, we need to make the total solution 500 liters (50 of the 500 would be a 10% solution). So we add 400 liters of water to the original 100 liter (50/50) solution. Take the total number of units and multiply by 4. Add that much in water.
Take 100 grams of 5% solution and do one of the following:Mix 95 g of it with 5 grams of sugar to end up with 100 g of 10% solution, or, when you are short of sugar:Evaporate 50 grams of water from 100 g of the 5% solution to end up with 50 g of 10% solution.
Let x be the amount of the 20% solution and y be the amount of the 65% solution. The total volume equation is: x + y = 500. The total amount of the solute equation is: 0.20x + 0.65y = 0.45(500). Solve these two equations to find the amounts of each solution needed.
To make a 5% (w/v) solution, you would dissolve 25 grams of sodium chloride (5% of 500 grams) in water to make a final volume of 500 mL. Sodium chloride has a molecular weight of 58.5 g/mol.
