Final answer:
To calculate the moles in one tablespoon of salt, divide the weight of the salt (6.37 g) by its molar mass (58.44 g/mol). The result is approximately 0.109 moles of salt in one tablespoon.
Step-by-step explanation:
The student is asking how to calculate the number of moles of table salt (NaCl) in one tablespoon, given that the molecular weight of NaCl is 58.5 g/mol and a tablespoon of salt weighs 6.37 grams. To find the number of moles, we need to use the formula:
Number of moles = Mass of substance (g) / Molar mass of substance (g/mol)
In this case, we take the mass of sodium chloride in the tablespoon, which is given as 6.37 grams, and divide it by the molar mass of NaCl, which is 58.44 g/mol.
Number of moles = 6.37 g / 58.44 g/mol
By performing the division, we find the number of moles of NaCl in one tablespoon:
Number of moles = 0.109 moles
Therefore, there are approximately 0.109 moles of table salt in one tablespoon.
