1. How much sodium is in one tbsp of salt?

To find out how much sodium is in one tablespoon of salt, we need to understand the composition of salt. Salt, chemically known as sodium chloride (NaCl), is composed of sodium and chloride ions.

To determine the amount of sodium, we need to consider the molecular weight of salt and the percentage of sodium present in it. The atomic weight of sodium (Na) is approximately 22.99 grams/mole, and the atomic weight of chlorine (Cl) is approximately 35.45 grams/mole.

The molecular weight of salt (NaCl) is the sum of the atomic weights of sodium and chlorine, which is 22.99 + 35.45 = 58.44 grams/mole.

Now, let's consider the composition of salt. Sodium chloride (NaCl) is approximately 40% sodium by weight. This means that for every 100 grams of salt, 40 grams is sodium.

Since one tablespoon of salt is about 14 grams, we can calculate the amount of sodium in one tablespoon of salt as follows:

(40 grams of sodium / 100 grams of salt) * 14 grams of salt = 5.6 grams of sodium

Therefore, approximately 5.6 grams of sodium are present in one tablespoon of table salt.
