Take 13.0 mL of the first solution ( 50 ug/mL) and dilute it up to 50.0 mL, you'll get the second solutionconcentration ( 13 ug/mL).
Proof: 13.0 mL x 50 ug/mL of 1st = 50.0 mL x 13 ug/mL of in 2nd
[Control: by units] 650 ug in 1st = 650 ug in 2nd
1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.
50 micrograms per millilitre is the same as 50*500 i.e. 25,000ug per 500ml. 25000ug is 25mg. In every ml, there are 50mg, so you only need half of a millilitre.
There are 0.8 milligrams in 800 micrograms.
34 US quarts contain a total of 32,176 milliliters. If each milliliter contains 45 micrograms, then thirty-four quarts will contain approximately 1.44792 grams of lead, though some portion of this will likely be lost if processes are used to extract it.
There are 1000 micrograms in a milligram. Therefore 5 micrograms is 0.005 milligrams.
You want 500ug i.e. 0.5mg/ml. You have 100mg. So you need 200ml of solvent. This is because 100/0.5*1 is 200ml.
1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.
they read at nano grams per milliliter (ng/ml) or micrograms?
First, 100ug per ul is 100,000ug per ml. You want 100 micrograms per ml. Therefore you need to dilute 1 in 1000. If 250ul is your total volume, you need to take 0.25 microlitres of the stock.
50 micrograms per millilitre is the same as 50*500 i.e. 25,000ug per 500ml. 25000ug is 25mg. In every ml, there are 50mg, so you only need half of a millilitre.
No, but it is on the NCAA's list of controlled substances. In a urine test, the NCAA accepts caffeine in levels up to 15 micrograms per milliliter.
There are 0.8 milligrams in 800 micrograms.
This question doesn't make sense. This is because the term parts per million means either weight per weight i.e. micrograms per gram or milligrams per kilograms, or weight per volume, i.e. milligrams per litre or micrograms per millilitre.
10.7 mg/L; both units of measure have been increased 1000-fold, so the order of magnitude remains the same.
So how much is your dilution factor? It is 0.028/100 or 28/100,000. So if you get a 10 litre volumetric flask (they exist), place 2.8ml of the 100mg/ml solution in and dilute it with 9.9972 litres of water. You can serially dilute, or use micropipettes in lower volumes. These may be more practical.
34 US quarts contain a total of 32,176 milliliters. If each milliliter contains 45 micrograms, then thirty-four quarts will contain approximately 1.44792 grams of lead, though some portion of this will likely be lost if processes are used to extract it.
12 micrograms per mililiter
