Question

Calculate the relative molecular mass of sodium chloride

Answer 1

Answer:

58.5

Explanation:

Relative mass of Na is 23

Relative mass of Cl is 35.5

So,relative mass of NaCl is (23+35.5)

=58.5

Answer 2

Answer:

Molecular mass of Sodium chloride:

molecular mass of Sodium = 23

molecular mass of chlorine = 35.5

So, the relative molecular mass of sodium chloride is :

= Ar (Na) + Ar ( Cl)

= 23 + 35.5

= 58.5g
