Anybody have access to CRC Handbook of Chemistry and Physics? I sold mine and only have the CRC Math Handbook on the shelf.
My calculation above is also off, I used molar mass of 258.06 g/mol which is true for anhydrous but I believe the correct value is 294.10 g/mol for dihydrate version of trisodium citrate. So that would change the percentage to 23.5% …
- 1 teaspoon = 4.93 ml
- Sodium citrate is 1.008 g/ml
- 4.969 grams of sodium citrate per teaspoon (4.93 x 1.008)
- using molecular weights of sodium citrate and 3 sodium atoms, by weight the sodium is 23.45% of sodium citrate (3 x 22.989 / 294.10)
- 1165mg of sodium in 1 teaspoon (4.93 x 1.008 x .2345)
ignoring granularity for example Cargill specs 60lbs/cubic-foot for granular and 58 lbs/cubic-foot for fine granular (the stuff I bought on Amazon looks to be fine granular).
Which bringing this back full circle the three estimates per teaspoon are:
- 1000mg rough estimate
- 1165mg from density and molecular weights of trisodium citrate dihydrate
- 1168mg from a label
