5 mg of an element or compound in 1 L of solution
.005 grams
3.2 ounces of chemical solution
Dissolve 17, 5 mg magnesium chloride anhydrous (reagent grade) in 1 L demineralized water, at 20 0C, in a vilumetric flask.
first calculate vd * CD =Vc * Cc Vc=50 * 2 / 5 =20ml
10,000 ppm
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.
.005 grams
Parts per million (ppm) is the same as mg/L. So, dissolve 5 mg of NaOH in 1 L of water and viola!
5000 mg = 5 ppm
You need to tell us what substance you want to convert.So we can calculate the molar mass.
3.2 ounces of chemical solution
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.

How much acid and chlorine should be added to a 5000 liter to make 5 ppm solution
what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
