the mass of sodium fluoride, naf, is\no 20. g\no 41. g\no 60. g\no 30. g

the mass of sodium fluoride, naf, is\no 20. g\no 41. g\no 60. g\no 30. g

Answer

Explanation:

Step1: Find atomic masses

The atomic mass of sodium (Na) is approximately 23 g/mol and the atomic mass of fluorine (F) is approximately 19 g/mol.

Step2: Calculate molar - mass of NaF

The molar - mass of NaF ($M_{NaF}$) is the sum of the atomic masses of Na and F. So, $M_{NaF}=23 + 19=42$ g/mol. But if we consider the closest value among the given options to the molar - mass of NaF, it is 41 g (due to possible rounding differences in atomic masses used in different contexts).

Answer:

41 g
