You use a conversion factor built into the full description of the problem which you have cleverly hidden from us.
There are 1000 micrograms in a milligram. Therefore, here you need to divide by 1000. 100/1000 is 0.1 milligram.
So there are 1000 nanograms in a microgram. Therefore 2ug is 2000ng. 2000ng divided by 100 is 20. There is a 20x dilution factor. So for every ml of stock, you dilute with 19ml solvent (total volume of 20ml).
To convert micrograms per square centimeter (ug/cm2) to parts per million (ppm), you need to know the density of the substance in question. First, you convert ug/cm2 to micrograms per cubic centimeter (ug/cm3) by dividing by the thickness of the material in centimeters. Then, you convert ug/cm3 to milligrams per cubic centimeter (mg/cm3) by dividing by 1000. Finally, you convert mg/cm3 to ppm by multiplying by the density of the substance in grams per cubic centimeter and then by 1,000,000.
A 1 percent solution of a medication means it contains 1 gram of the medication in 100 mL of solution. To convert grams to micrograms, you multiply by 1,000,000. Therefore, a 1 percent solution would contain 1,000,000 micrograms of the medication.
There are 1000 micrograms in a milligram. Therefore 100 milligrams is going to equal 100,000 micrograms.
There are one million micrograms to one gram. 100 micrograms is 0.0001 of a gram.
You have to convert milligrams to micrograms here. Therefore 0.02mg is 20 micrograms. There are 5 x 0.02mg in 100 micrograms.
There are 1000 micrograms in a milligram. Therefore, here you need to divide by 1000. 100/1000 is 0.1 milligram.
So first off we need to convert milligrams to micrograms. 100mgx1000 is 100,000 micrograms. 40/100,000 is 1/2500 of a pill.
There are 0.1mg in 100 micrograms (ug). You have to divide by 1000 to convert ug to mg.
Oh, dude, it's super easy. So, like, 100 micrograms (ug) is the same as 0.1 milligrams (mg). You just move the decimal place three spots to the left because micro is like super tiny compared to milli. So, yeah, 100 ug is 0.1 mg. Easy peasy.
No, it is not. When the prefix changes, you know it's the decimal places or the amount of zeroes that changes, and not the figure itself. i.e. the first significant figure in each is 1 and 5 respectively, so this cannot be correct. 100 micrograms is actually 0.1 and not 0.5 milligrams.
There are 1000 micrograms in one milligram. Therefore, 100 micrograms is equal to 100/1000 = 0.1 milligrams.
There are 100 micrograms in 0.1 mg.
So there are 1000 nanograms in a microgram. Therefore 2ug is 2000ng. 2000ng divided by 100 is 20. There is a 20x dilution factor. So for every ml of stock, you dilute with 19ml solvent (total volume of 20ml).
There are 1000 micrograms in a milligram. Here, you must multiply by 1000. 100*1000 is 100,000 micrograms.
100 micrograms is equal to 0.0001 grams.
