You haven't specified the molecular weight, or even the compound in question. If you find this out, divide by the molecular weight to get your answer.
1ug=10^-6g Therefore 10ug would equal 0.00001g
Epulopiscium fishelsoni lives in the gut of Red Sea surgeonfish and is 0.6 mm long and 0.08 mm in diameter. http://en.wikipedia.org/wiki/Epulopiscium_fishelsoni
First, divide the number micrograms by 1000 to get grams. Then divide the number of grams by the molar mass of the compound to get the number of moles. Finally, multiply the number of moles by 1000 to get micromoles. See the related question below this answer for more details.

No. Micromolar is a measure of micromoles per liter, not micrograms per liter. To convert between micrograms and micromoles, use the molar mass of the substance.
You need to get the molecular weight of carbon. This is 12g/mol. Gram per mole is the same as microgram per micromole. So you divide micrograms by 12 to get your answer in micromoles.
To convert grams to moles you need the molecular mass. Firstly you need to convert 350 picomoles to micromoles. 350/1,000,000 is 0.000350 micromoles. Then you multiply by the molecular weight of the compound.
1 moles selenium = 78.96 g1 mmole = 78.96 mg1 micromole = 78.96 micrograms0.4 micomoles x 78.96 micrograms/micromole = 31.58 micrograms = 30 micrograms (to 1 sig.fig.)
There are 1000 micrograms in a milligram. Therefore there are 0.02 milligrams in 20 micrograms.
There are 1000000 micrograms in one gram. Therefore, 20 micrograms is equal to 20/1000000 = 0.00002 grams.
There are 1000000 micrograms in one gram. Therefore, 20 micrograms is equal to 20/1000000 = 0.00002 grams.
20,000,000 micrograms = 20 grams.
There are 1000 micromoles in a millimole. Therefore you have to multiply by 1000. 0.59mmol is 0.59x1000 or 590 micromoles.
There are 1000 micrograms in a milligram. Therefore 20 micrograms is 0.03 milligrams.
There are 1000 micrograms in a milligram. Here, you need to divide by 1000. 20/1000 is 0.02 milligrams.
You have to convert milligrams to micrograms here. Therefore 0.02mg is 20 micrograms. There are 5 x 0.02mg in 100 micrograms.
