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
Pure table salt obtained from rock salt or sea water are similar - sodium chloride, NaCl. It is not necessary to prepare a homemade sea salt (excepting the situations when other salt doesn't exist).
The preparation of insoluble salt can be done by PRECIPITATION METHOD
If the membrane in a beaker were impermeable the concentration of salt parts on either side will not change

Yes The amount of salt in a salt water pool is about 3,000 parts per million the average bowl of soup has far more salt in it.
Mango trees shouldnot be watered with water from wells containing 2,300 ppm ormore of salt.
The salt used to prepare a mummy is sodium carbonate not sodium chloride.
use a tds total dissolved solids meter. this will give you the salts ppm
When you want to dissolve salt, you use water as the solvent, and salt is therefore the solute.
There are 7 million salt mines.
Most systems use 2500 to 6000 parts per million, that would be way less than 1 percent
Rivers are fresh water.
Many food companies offer balsamic salt; the variety is infinite. You can prepare also balsamic salt at home after your preferences.
