for 1000 grams of tear water, hom many grams of salt?

Answer 1

Of the various salts found in solution in bodily fluids, by far the commonest is table salt, or sodium chloride (NaCl). On average there is a little over 6 milligrams (mg) of NaCl dissolved in each millilitre (ml) of lacrimal fluid (tear fluid),

So 0.006mg *1000g(density of tears is 1g/cm3 the salt is negligiblein the differance to density) = 6g NaCL (Salt)
