Milli means 1/1000 (compare millimetres), so it's 1/10 mole
Millimole is 1000th of a mole which is 10^-3
Ag+ = 50 x 0.05 = 2.5 millimoles CrO4^2- = 100 x 0.06 = 6 millimoles Ag2CrO4 moles = 1.25 x 10^-3 moles formed.
You obtain 10 millimoles of ferric chloride and dissolve it in a liter of water.
Millimoles are a unit of measurement based of mole, which measures the amount of substance in something that has an equal number of atoms and elementary entities. Millimoles are calculated by multiplying the amount of moles by 1,000.
Millimole per litre is a unit for small concentrations; sometimes used for pharmaceutical solutions.
100 millimoles is 0.1 moles. To convert moles to grams, you need to multiply by the molecular weight, in this case, 194.22g/mol. 0.1*194.22 is 19.422 grams.
There are 1000 millimoles in a mole. So you need to divide by 1000 here. 1250 millimoles / 1000 is 1.25 moles.
Millimole is 1000th of a mole which is 10^-3
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

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.
Ag+ = 50 x 0.05 = 2.5 millimoles CrO4^2- = 100 x 0.06 = 6 millimoles Ag2CrO4 moles = 1.25 x 10^-3 moles formed.
The molecular weight of water is 18g/mol. There are 0.00325 moles in 3.25 millimoles. 0.00325*18 is 0.0585 grams. This is 0.0000585 kilograms.
Approx. 12 millimoles/L.
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.
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
Assuming that "mM" means "millimolar", the solution specified contains 6 millimoles of ammonium sulphate per liter. Therefore, 25 ml of the solution contains 6(25/1000) = 0.15 millimoles. By definition, there are 1000 micromoles per millimole. Therefore, 0.15 millimoles = 150 micromoles.
