How many sodium chloride (NaCl) molecules are in a tablespoon?

1. A tablespoon of salt contains about 30 g of salt;

2.Calculate the chemical amount of sodium chloride:

n (NaCl) = m (NaCl): M (NaCl);

M (NaCl) = 23 + 35.5 = 58.5 g / mol;

n (NaCl) = 30: 58.5 = 0.5128 mol;

3.determine the number of molecules of a portion of table salt:

N (NaCl) = n (NaCl) * Na = 0.5128 * 6.02 * 10 ^ 23 = 3.087 * 10 ^ 23.

Answer: 3.087 * 10 ^ 23.
