Question

What is the molecular mass & atomicity of :-
1) FeSo4.7H2o
2) Cacl2
3) Na2znO2
4) Ca3(Po4)2
5) (NH4)3.Po4
6) Zn(OH)
7) HgS
8) Hg2S
9) Ag3.Po4.2H2O
10) CCl4
And what is the name of above copounds?

Answer 1

Calculating molar mass is lengthy but the names are

Iron(||)sulfate

calcium chloride

sodium zincate

calcium phosphate

di ammonium phosphate

zinc hydroxide

mercury sulfide

mercury (||) sulfide

Silver phosphate

carbon tetra chloride

and mass of

fe = 23

s = 32

h = 1

o = 16

ca = 40

cl = 35.5

na = 23

zn = 65

p = 31

ag = 108(107.8)

hg = 200.6=201

c = 12
