To calculate the molecular mass of sodium chloride (NaCl), we need to add up the atomic masses of sodium (Na) and chlorine (Cl).
The atomic mass of sodium (Na) is 22.99 amu, and since there are two sodium atoms in the compound, we multiply this by 2:
2 x 22.99 amu = 45.98 amu
The atomic mass of chlorine (Cl) is 35.45 amu, and since there is only one chlorine atom in the compound, we multiply this by 1:
1 x 35.45 amu = 35.45 amu
Adding up the atomic masses of sodium and chlorine, we get:
45.98 amu + 35.45 amu = 81.43 amu
Therefore, the molecular mass of sodium chloride (NaCl) is 81.43 amu.
None of the given options match the calculated molecular mass of sodium chloride.

The atomic mass of chlorine (Cl) is 35.45 amu, and since there is only one chlorine molecule (Cl2) in the equation, we use the atomic mass of Cl2:
35.45 amu x 2 = 70.9 amu
Adding up the atomic masses, we get:
45.98 amu + 70.9 amu = 116.88 amu
Therefore, the molecular mass of sodium chloride (NaCl) is 116.88 amu.
So the correct answer is A) 116.88 amu.
