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.
4500 micrograms is equivalent to 4.5 milligrams.
1ug=10^-6g Therefore 10ug would equal 0.00001g
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.
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
It receives 20 chromosomes from each parent (20 from father)
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.)
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.
To convert micrograms (μg) to micromoles (μmol), you need to know the molar mass of the substance. First, convert micrograms to grams by dividing by 1,000,000. Then, divide the grams by the molar mass to get micromoles. The formula is: micromoles = (micrograms / molar mass).
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.
There are 1000000 micrograms in one gram. Therefore, 20 micrograms is equal to 20/1000000 = 0.00002 grams.
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.
20,000,000 micrograms = 20 grams.
There are 1000 micrograms in a milligram. Here, you need to divide by 1000. 20/1000 is 0.02 milligrams.
There are 1000 micromoles in a millimole. Therefore you have to multiply by 1000. 0.59mmol is 0.59x1000 or 590 micromoles.
800 IU of vitamin D is equivalent to 20 micrograms (mcg).
