1 mEq=1 mmol/valence
e.g.For sodium,
1 mEq=1mmol/1 (valence of sodium=1)
means, 1 mmol sodium=1 mEq of sodium
take for calcium,valence=2
1 1 mEq of calcium=1mmol/2=0.5 mmol of calcium
To do this, you use the following information: * You know that one mol contains about N_A = 6.022 * 10^{23} particles (one mmol is 1/1000 of a mol) * You look up the atomic weight of the particles you are interested in, in order to know the mass m_p of a single one of your particles Then you know that the mass m of all the particles in your system corresponds to a number of particles N = m / m_p and that this number of particles N is equivalent to (N/N_A) mol = 1000*(N/N_A) mmol
25 mg to mmol
A2: The unit for formula weight is g/mol. If you want mg/mmol, you need to mutiply by 1000.
mmol (mol/1000 mmol)
25 mmol equates to 0.025 mol
3.5 mol x (1000mmol/1mol) = 3500mmol
12.5 mL * 5.0 (m)mol/(m)L HCl = 62.5 mmol spilled HClneeds62.5 mmol NaHCO3 = 62.5 mmol * 84.01 (m)g/(m)mol NaHCO3 = 5250 mg NaHCO3 = 5.25 g pure NaHCO3
Using V * M = constant at dilution = amount of H2SO4 [mol] in both of the solutionsV= volume [L] of the solutionM= molarity [mol/L] of the solutionSo: V *18.0 = 24.9 * 0.195 gives V = ( 24.9 * 0.195 ) / 18.0 = 0.270 L
0.1 % equals 22 mmol so 10.9 mmol is just a hair below 0.05%
1 mol = 103 mmol Conversely, 1 mmol = 10-3 mol For example: 25 mol x 103 mmol/1 mol = 25000 mmol and, 3.2 mmol x 10-3 mol/1 mmol = 0.0032 mol
25 mmol equates to 0.025 mol
1000 mmol = 1 mol. So, what you do is 2.55mmol*(1mol/1000mmol). The mmol's cancel and you are left with mol. The "m" is a metric prefix. So, 1000mN = 1N just like 1000mmol = 1mol.
formula for to convert gm to mmol
3.5 mol x (1000mmol/1mol) = 3500mmol
10500
To convert from mmol (millimoles) to nmol (nanomoles), you simply multiply the value in mmol by 1000000. This is because there are 1000000 nmol in 1 mmol.
what is the factor ( times ) to convert milligrams/DeciLitre to mmol/L
This means that the conversion factor depends on the molecular weight of the substance in question. To convert mgd to mmol we multiply by 0.055.

divide the mg of creatinine by 113 mg/mmol (molecular weight) of creatinine and the units will be in mmol
