                                   OR

To two decimal places, the formula mass of NaCl is 58.44 amu

Answer 2

Given: 2NaCl

To find: We have to find the atomic mass of 2NaCl.

the atomic mass of 2NaCl.Solution:

NaCl is a salt of strong base Sodium hydroxide and strong acid Hydrochloric acid.

1 mole of NaOH reacts with 1 mole of HCl to form NaCl.

The atomic mass of 1 mole of NaCl is the sum of the atomic mass of Na and Cl.

The mass of the Na atom is 22.98 and the mass of the Cl atom is 35.45.

So, the atomic mass of 1NaCl is 22.98+35.45=58.43The atomic mass of 2NaCl is 58.43×2=116.86

So, the atomic mass of 2NaCl is 116.86amu.
