Answer:

The number of moles of salt in one tablespoon is 0.1089.

Explanation:

Molar weight of the table salt = 58.5 g/mol

Mass of the table salt in 1 table spoon = 6.37 grams.

Moles of NaCl = [tex]\frac{6.37 g}{58.5 g/mol}=0.1089 mol[/tex]

1 table spoon = 0.1089 moles of NaCl

The number of moles of salt in one tablespoon is 0.1089.

The number of moles of salt in one tablespoon would be 0.109 moles

Recall that the number of moles of a substance is the ratio of the mass of the substance and that of its molecular mass.

In other words:

Number of moles = mass/molar mass

In this case, the molar mass is given as 58.5 g/mole while the mass of a tablespoon of NaCl is 6.37 grams.

Hence,

Number of moles of NaCl is a tablespoon = 6.37/58.5

= 0.109 moles
