Answer:
(a)KOH
Molecular mass
of KOH = 39 +16 +1 = 56u
(b) Molecular mass of
= 23 + 1 + 12
+ 3 x 16
= 23 + 1 + 12
+ 48 = 84 u
(c) , Molecular mass of
= 40 +12 + 3
x 16 = 100 u
(d) NaOH Molecular
mass of NaOH
= 23 + 16 +1
= 40 u
(e) Molecular mass of or
= 2 x 12 + 6
x 1 + 16
= 24 + 6 + 16
= 46 u
(f) NaCI
Molecular mass of
NaCl =23+35.5 =58.5 u
