From my husband, a Ph.d/MIT chemist:

To make 0.9% saline (weight/weight percent)

.9 g NaCl / 100 g water    = 1.5 g  / 166 ml


1/4 teaspoon of salt (i.e. 1.5 g) dissolved in 166 ml of water.


**************** APPROXIMATELY  :****************

 1/4 teaspoon salt in 2/3 cup water

or

 3/4 teaspoon salt in 2 cups water.

or

 a heaping 1/4 teaspoon in 1 cup water.
