- Common mistake was to look up the amount of sodium in an amp of bicarb, 50 mmol, but that will not tell you the concentration, which you have to divide by the volume, 50 mL, giving 1,000 mmol/L
- — Joel Topf (@kidney_boy)Wed, Jun 18 2014 20:06:06@amandasxi The bicarbonate is wrong. 50 mEq NaHCO3 in an amp of bicarbonate but the volume is only 50ml so concentration is 1,000 mEq/L.
- But I made the same mistake in my analysis of soup. I remember my post about chicken noodle soup and that a couple of servings was equal to a bag of half normal saline, but that post was about sodium content not concentration. In fact Amanda Xi was right that soup is essentially isotonic.
- I gave a hint.

- When I gave my answer it became my most retweeted tweet ever
Fun with Twitter: Guess how salty?
So I asked Twitter arrange 5 solutions from the highest sodium concentration to the lowest sodium concentration.
