There is not enough information. To convert a mass (mg) into a volume (L) you require the density of the substance you are measuring.
620 (mg per liter) = 62 mg per deciliter.
10mg/0.5mg = 20
5mg :)
1 liter = 1000 mL 1 gram = 1000 mg So there are 45,000 mg in 1 liter divided by 1000 mg per gram = 45 grams/liter
50 mg
1 mg = 1,000 ug 1 mg per Liter = 1,000 ug per Liter. 1 mg per Liter is 1,000 times as concentrated as 1 ug per Liter.
To make 0.25 mg from 0.5 mg, you would need to use half of the 0.5 mg dosage. Therefore, you can consider that 0.5 mg contains two 0.25 mg doses. So, it takes 0.5 mg to make 0.25 mg, but you only need to use half of it.
100 mg is 1/10 gram, so 20 grams is 200 x 100 mg.
10000 litres * 5 mg/1 litre * 1 g/1000 mg = 50 grammes.
No. A mg (milligram) is a measure of weight; a liter is a measure of volume.
mg is milligram, a measure of weight. Liter is a measure of volume. A liter of WATER would weigh 1 million milligrams- but a liter of alcohol would weigh about 700,000 mg- since alcohol is lighter than water. A liter of mercury would weigh MUCH more, since it is heavier than water. So, to answer your question, we would need to know a liter of WHAT?
It depends on the volume of solvent.
