Find the formula mass of
(i) KCI
(ii) AgCi
Atomic mass of K = 39 u, Ag = 108 u and
CI = 35.5 u.

Answer 1

Explanation:

Formula mass of KCl:

molar mass of K=39amu

molar mass of Cl=35.5amu

So KCl=39+35.5

=74.5 amu

Formula mass of AgCl2:

Molar mass of Ag= 108 amu

Molar mass of Cl=35.5amu

So,AgCl2= 108 + 2(35.5)

=179 amu
