Answer:

35.5+23.0=58.5 ......................

Please make my answer Brainlist.

Answer 2

Given:

Atomic mass of chlorine = 35.5 atomic mass unit

Atomic mass of sodium = 23.0 atomic mass unit

To Find:

Mass of 1 NaCl

Solution:

Atomic mass of an atom is the count of number of electron and proton of that atom taken together.

Here in this question we have to find the atomic mass of NaCl

Mass of 1 unit of NaCl = Atomic mass of Na + atomic mass of Cl

=23u+35.5u

=58.5u

Hence, the mass of one NaCl unit is 58.5u
