You haven't stated the compound or molecular weight. The formula you need is the number of moles = mass / molecular mass. If you have millimoles, multiplying by molecular weight will convert to milligrams.
Grams to go like this. From smallest to largest. Micrograms (Mcg), Milligrams (Mg), and then Grams (G). To answer your question. You have it backwards. 1,000Mcg makes 1Mg and 1,000Mg makes 1G. I hope that answers your questions.
Micro means 1/1000000. Milli means 1/1000. So there is actually just 1 milligram in 1000 micrograms.
There are 1000 microgram in ever milligram. Therefore 1000/1000 will give you one milligram.
It is 1 milligram. There are 1000 micrograms in a milligram. This is because there are 1000000 micrograms in a gram and there are 1000 milligrams in a gram.
there are 1000 milligrams in one gram. soooo... there would be... 0.001 grams in 1 milligram.
1000 milligrams = 1 gram. Read "one thousand milligrams equals one gram".
There are 10 milligrams in a centigram. Therefore 8500 milligrams is 850 centigrams.
One kilogram is equal to 1000 x 1000 = 1000000 milligrams. Therefore, 5.6 kilograms is equal to 5.6 x 1000000 = 5600000 milligrams.
A milligram is a measure of mass, not of weight. So there is nothing that weighs 1000 milligrams.
There are 1000 millimoles in a mole. So you need to divide by 1000 here. 1250 millimoles / 1000 is 1.25 moles.
You need to divide by 1000 here. This is because there are 1000 millimoles in a mole. 2.55/1000 gives you 0.00255 moles.
You haven't given the compound or the volume so I'll talk you through it. Forst off when you have the volume, you'll divide 10 by 1000 and multiply by the amount of mls that you have. Then you'll divide by 1000 to get it in millimoles. Then you'll multiply by the molecular weight to convert to milligrams.
First off you multiply moles by 1000 to convert to millimoles. Next you multiply by the molecular weight (found as the bigger figure on the element on the periodic table).
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.125 grams Ca / (40.1 grams) = 3.12 moles Ca
1000 milligrams = 1 gram
There are 1000 milligrams in a gram. Therefore 1000 grams is 1,000,000 milligrams.
Because the formula for calculating moles is dividing grams by the molecular weight. The molecular weight for glucose is 180. grams to moles is also the same as milligrams to millimoles.
There are 1000 milligrams in one gram. Therefore, 1.3 milligrams is equal to 1.3/1000 = 0.0013 grams.
So molar means moles per litre. So you have to divide by 1000 and multiply by 0.2. 0.5/1000*0.2 is 0.001 millimoles of glycine in your 0.2 millilitres.
1000 milligrams = 1 gram 109 grams x 1000 milligrams = 109000 grams 109 grams x 1000 milligrams = 109000 milligrams
There are 1000 milligrams in a gram. Therefore you have to multiply grams by 1000. 487*1000 is 487,000 milligrams.
