How do you prepare 125 parts per million Fe from the salt Fe(NH4)2(SO4)2.6H2O?
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
How many mg in 0.2 mmol of Te?
The answer is 0,02552 mmol.
2.55 mmol to moles?
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.
What is the number of grams in 54.9 mmol SO2?
54,9 mmol of sulfur dioxide is equivalent to 3,517 g.
What is the mass of 10 mmol solution?
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.
How many grams of anhydrous sodium sulphate should be used to prepare Sodium sulphate solution 60ml where Each ml contains 0.1mmol of Na plus?
To calculate the mass of anhydrous sodium sulfate needed, you first need to determine the total moles of Na+ required. In this case, 60 ml * 0.1 mmol/ml = 6 mmol of Na+. Anhydrous sodium sulfate has a molecular weight of 142.04 g/mol, so you will need 6 mmol * 142.04 g/mol = 852.24 mg or 0.85224 grams of anhydrous sodium sulfate to prepare the 60ml solution.
How much sodium bicarbonate would be required to prepare 500ml of a 100mM solution?
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

How do you convert mmol to nmol?
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.
How do you convert mmol to milliters?
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
How many mg in 0.2 mmol of Te?
The answer is 0,02552 mmol.
What is 25 mmol converted to mol?
25 mmol equates to 0.025 mol
Is mmol EDTA the same as mmol Ca2?
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.
How many mg for 4.12 mmol?
4.12 mmol is 2.48112242e+24mg
How many mg of sodium in an 87 mmol diet?
To convert mmol of sodium to mg, use the conversion factor: 1 mmol = 23 mg. Therefore, in an 87 mmol diet, there would be 87 mmol × 23 mg/mmole = 2001 mg of sodium.
How many mmol are in 3.5 mol?
There are 3500 mmol in 3.5 mol. To convert mol to mmol, you multiply by 1000 since there are 1000 mmol in 1 mol.
2.55 mmol to moles?
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.
