Could anybody please help me how to "make" seawater from tap water. I know
the concentrations of the different minerals in seawater in units of parts
per thousand (the info is in  Encarta) but I need to know which raw
materials to use and in what concentration, ie. mg of mineral per
deciliter of water.

Please email response to [email-masked]

I would suggest you post a question in sci.geo.oceanography, asking
where you can find 'Copenhagen water'.  It is the standard of seawater
used in calibration of conductivity sensors for oceanographic instruments.
Probably too expensive, so why not gather some sea salt?

I imagine your best bet would be to go to a fish store and purchase
some "Instant Ocean" or equivalent.  That will get you as close to
seawater as you can get short of a trip offshore.  This is a commonly
sold item for saltwater fish hobbiests.  Hope this helps,

The simplest thing to do is to realise that 1 liter of water weighs 1
kilogram (1000 grams).  If a solute in seawater is 4 parts per thousand, 4
grams of solute in 996 grams (ml) of water prepares the correct
concentration.  The resultant solution will weigh 1000 grams of which 4
grams will be solute (4 parts per thousand).
