Question

Deduce the molecular masses of

1.) NaCl
2.)MgCl2

Answer 1

Hello friend

___________________________


i.) NaCl

==> Molecular mass of NaCl

==> (Atomic mass of Na) x 1+(Atomic mass of Cl) x 1

==> (23 x 1) + ( 35.5 x 1)

==> 23 + 35.5

==> 58.5


: Molecular mass of NaCl = 58.5


ii.) MgCl2

==> Molecular mass of MgCl2

==> (Atomic mass of Mg) x 1 +(Atomic mass of Cl) x 2

==> (24 x 1) + (35.5 x 2)

==> 24 + 71

==> 95


: Molecular mass of MgCl2 = 95


Thanks...
