Dissolve 17, 5 mg magnesium chloride anhydrous (reagent grade) in 1 L demineralized water, at 20 0C, in a vilumetric flask.
5 mg of an element or compound in 1 L of solution
5 ppm means that there are 5 grams of solute in every 1 million grams of solution. Therefore, in a 1000-gram solution, the total mass of solute would be 0.005 grams.
To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
For sanitizing work surfaces, a common concentration of bleach solution is 1000-5000 ppm (parts per million). This means mixing 1 teaspoon of bleach with 1 gallon of water (for 1000 ppm) up to 5 teaspoons of bleach with 1 gallon of water (for 5000 ppm). Always ensure proper ventilation and follow manufacturer's instructions for safe and effective use.
To convert from cmol/kg to ppm for calcium (Ca): 1 cmol/kg of Ca = 40.08 mg/kg 40.08 mg/kg = 40.08 ppm So, 5 cmol/kg of Ca is equal to 200.4 ppm.
5 parts per million (ppm) is the same as 5 milligrams per kilogram (mg/kg) for a solution.
A solution that is refered to as a percentage of something (like potassium hydroxide, KOH) refers to the mass of the solute compared to the total solution, so a 5% KOH solution would be 5g KOH + 95g H2O, and the 5g KOH would be 5% of the 100g total of the solution.
5 mg of an element or compound in 1 L of solution
Make a 1 to 100 dilution of the original 1000 ppm solution. That is take 1 ml and dilute to 100 ml, or take 10 ml and dilute to 1000 ml. This will give you a 10 ppm solution.
To prepare a 5% potassium iodide solution, weigh 5 grams of potassium iodide and dissolve it in 100 mL of water. Stir until the potassium iodide is completely dissolved to achieve a 5% solution.
To prepare a 5 ppm sodium hydroxide solution, you would need to dissolve a small amount of sodium hydroxide in a larger volume of water. For example, to make 1 liter of 5 ppm solution, you would add 5 mg of sodium hydroxide to the water. It's crucial to accurately measure both the sodium hydroxide and the water to ensure the final concentration is correct.
5 ppm means that there are 5 grams of solute in every 1 million grams of solution. Therefore, in a 1000-gram solution, the total mass of solute would be 0.005 grams.
How much acid and chlorine should be added to a 5000 liter to make 5 ppm solution
When potassium manganate is mixed with water, it dissolves to form a purple solution. Over time, the solution may slowly turn colorless as the potassium manganate reacts with water and other substances present in the solution.
To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
Divide ppm by 10,000:50,000 / 10,000 = 5 %
10,000 ppm Solution Method: 1. A ppm = 1/1,000,000 = 0.000001 2. What you want to know is: how many ppm would = 1% 3. p * .000001 = .01 4. p = .01 / .000001 5. p = 10,000 You could also do it this way: 1. 1% of 1,000,000 = ppm = 10,000 ppm (but that method lacks a clear path to understanding). === previous answer's method: 1%=1/100=1000000/100=10000ppm.
