Question

1 mole of sodium chloride is represented as [Na = 23u,Cl=35.5 u]

Answer 1

Answer:

NaCl is the answer but not confirm

Answer 2

1 mole of sodium chloride is represented as a mass of 58.5 grams.

Explanation:

• The base unit of amount of substance is mole.
• 6.022×10²³ units is equal to one mole of a substance.
• Atomic mass of sodium Na is 23amu and chloride Cl is 35.5amu.
• Hence, molar mass of sodium chloride NaCl is the sum of atomic mass of sodium and chloride.
• Molar mass of NaCl = atomic mass of Na + atomic mass of chloride.
• Molar mass of NaCl = 23+35.5 = 58.5amu.
• Thus, the mass of sodium chloride is 58.5 grams.
