The mass of a 10 mmol solution will depend on the molar mass of the solute. To calculate the mass, multiply the number of moles (10 mmol) by the molar mass of the solute in grams/mole.
To convert grams (g) to millimoles per liter (mmol/L) for a substance, you need to know the molar mass of the substance. Then you can use the formula: Concentration in mmol/L = (mass in g) / (molar mass in g/mol) * 1000.
Molar mass Fe is 55.845 mg/mmol, so 125 mg represents 125 / 55.845 = 2.238 mmol Fe.Since the molar mass of (NH4)2Fe(SO4)2·6H2O is 392.13 g/mol, 2.238 mmol of this Mohr's salt weights 392.13(mg/mmol) * 2.238 mmol = 878 mg Mohr's salt.This has to be dissolved in 1.00 L water to give the desired 125 ppm (=mg/L) Fe2+ solution
To calculate 1 millimolar (mM) concentration of a substance, you need to know the molar mass of the substance. Then, divide 1 millimole (mmol) by the molar mass to obtain the volume of the substance needed to make a 1 mM solution.
To convert milligrams (mg) of urea to millimoles (mmol) of urea, you need to know the molar mass of urea, which is 60.06 g/mol. Divide the mass in mg by the molar mass to get the amount in millimoles. For example, to convert 100 mg of urea to mmol, you would divide 100 mg by 60.06 g/mol to get approximately 1.67 mmol of urea.
The percentage by mass of the solute in an aqueous solution of potassium sulfate indicates the mass of potassium sulfate present in a given mass of the solution. For example, a 10% by mass solution means that there are 10 grams of potassium sulfate for every 100 grams of solution. This measurement provides a clear indication of the concentration, allowing for comparisons between different solutions and helping in calculations for reactions or processes that require specific concentrations.
To convert grams (g) to millimoles per liter (mmol/L) for a substance, you need to know the molar mass of the substance. Then you can use the formula: Concentration in mmol/L = (mass in g) / (molar mass in g/mol) * 1000.
Molar mass Fe is 55.845 mg/mmol, so 125 mg represents 125 / 55.845 = 2.238 mmol Fe.Since the molar mass of (NH4)2Fe(SO4)2·6H2O is 392.13 g/mol, 2.238 mmol of this Mohr's salt weights 392.13(mg/mmol) * 2.238 mmol = 878 mg Mohr's salt.This has to be dissolved in 1.00 L water to give the desired 125 ppm (=mg/L) Fe2+ solution
No, mmol EDTA refers to the amount of EDTA (ethylene diamine tetraacetic acid) present, while mmol Ca2+ refers to the amount of calcium ions present in a solution. They are not the same and represent different chemical species.
500 mL * 100(mMol/mL) = 50 mMol NaHCO3 , hence50 mMol NaHCO3 = 50(mMol) * 84(mg/mMol) = 4200 mg = 4.2 g NaHCO3 in 500 mL
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
To convert mmol to grams, multiply by the molar mass. The molar mass of sodium is approximately 23 g/mol. Therefore, 80 mmol of sodium is equal to 80 mmol * 23 g/mol = 1840 grams of salt (sodium chloride).
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.
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
To calculate 1 millimolar (mM) concentration of a substance, you need to know the molar mass of the substance. Then, divide 1 millimole (mmol) by the molar mass to obtain the volume of the substance needed to make a 1 mM solution.
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 convert from mg to mmol for creatinine, you need to know the molecular weight (MW) of creatinine, which is 113 g/mol. To convert, divide the mass in milligrams (mg) by the molecular weight in milligrams per mmol (113 mg/mmol). For example, if you have 100 mg of creatinine, the conversion would be 100 mg / 113 mg/mmol = 0.88 mmol.
Sodium is monofunctional. Thus its molecular weight and equivalent weight are identical. So there are 10 milliequivalents of sodium in 10 millimoles.
