Q.9. Calculate the molar mass of NaCl

O 58.44gm/mole

O23.403 gm/ mole

O 35.45gm/mole

O 18gm/mole

Answer 1

58.44 g/mole

Step-by-step explanation:

To calculate the molar mass of NaCl (sodium chloride), we need to find the sum of the atomic masses of sodium (Na) and chlorine (Cl) off the periodic table.

Atomic mass of Na = 22.99 g/mol

Atomic mass of Cl = 35.45 g/mol

Molar mass of NaCl = Atomic mass of Na + Atomic mass of Cl

= 22.99 g/mol + 35.45 g/mol

= 58.44 g/mol

Therefore, the molar mass of NaCl is 58.44 g/mol.
