Is the percentage of sodium in pure table salt 39.34%?

what is 23/(23+35) ?

To determine the percentage of sodium in pure table salt, we first need to understand the chemical composition of table salt. Table salt, also called sodium chloride (NaCl), is composed of sodium (Na) and chloride (Cl).

The atomic mass of sodium (Na) is approximately 22.99 grams per mole, while the atomic mass of chlorine (Cl) is approximately 35.45 grams per mole.

To calculate the percentage of sodium in table salt, we need to compare the atomic mass of sodium with the molar mass of table salt (which is the sum of the atomic masses of sodium and chlorine). The molar mass of NaCl can be calculated as follows:

Na: 1 atom * 22.99 g/mol = 22.99 g/mol
Cl: 1 atom * 35.45 g/mol = 35.45 g/mol

Molar mass of NaCl: 22.99 g/mol + 35.45 g/mol = 58.44 g/mol

Now, let's calculate the percentage of sodium in table salt. To do this, we divide the molar mass of sodium by the molar mass of table salt and multiply by 100:

(22.99 g/mol / 58.44 g/mol) * 100 = 39.39%

So, the correct percentage of sodium in pure table salt is approximately 39.39%, not 39.34%.
