The amount of salt in a physiologic solution is 9 or 8.5 g per quart. 😁 😁 😁
The amount of salt that goes into a physiologic solution is incredibly easy to find on the internet in a number of places and because it has also come up on Zity a number of times. I have been telling people to get a digital scale for years. Be a sport. For 25 bucks you can own one.
Different salts have different densities.
Did you know:
1 tsp of Maldon sea salt flakes is only 3 grams
1 tsp of Morton Kosher salt is 6 grams
1 tsp of Diamond Crystal Kosher salt is 5 grams
1 tsp of Diamond Crystal regular salt is 5 grams
1 tsp of Morton Ice Cream rock salt is 8 grams
1 tsp of Sherpa Pink Himalayan rock salt is 6 grams
1 tsp of Spice Lab pink Himalayan fine salt is 6 grams
The density of pure NaCl is 2.15g/cc. With 4.93 cc in a teaspoon, It isn't surprising that the Morton Ice Cream Rock salt weighs in at 8g per teaspoon.
ALL THE SALTS ARE DIFFERENT.
I have weighed most if them.
NONE of the salts including Morton's iodized is 9 grams per teaspoon. Sorry, but I don't trust how accurately you scraped the salt on top of your "level measuring teaspoon" as an accurate way to measure this.
That's why it's 9 grams -- EXACTLY
------------
Your elevation of 760 feet added to 4000 miles of the earth's radius has essentially ZERO effect on the weight of an object (one teaspoon of salt). Since you mentioned your elevation above sea level you should know that.
I estimate that 9 grams of salt at sea level will weigh ROUGHLY 8.9999999 grams at 760 feet above sea level owing to the increased distance from the center of the earth's mass than at sea level.
4000 miles plus 0.14 miles (your elevation of 760 feet) creates an EXTREMELY small difference in weight. YOU can look up the formula and do the math.
