Question

write the formula of the following and calculate molecular mass
1. calcium carbonate
2.magnesium phosphate
3.ferric chloride

Answer 1

Hi friend,

1) Formula of Calcium carbonate :-
CaCo3
Moleculer mass :- 100.0869 g/mole


2) Formula of Magnesium Phosphate ;-
Mg3( Po4)2

Moleculer mass:- 24.3050*3 + ( 30.973761 + 15.9994*4)*2 = 262.857722 g/mole

3) Formula of Ferric Chloride ;-
FeCl3.
Moleculer mass :- 55.845 + 35.453*3 = 162.204 g/mloe


.....i hope it helps you

Answer 2

1) Calcium carbonate - CaCo3 .
Molecular Mass = 100.0869 g/mol

2) Magnesium Phosphate -Mg3(PO4)2
Molecular Mass= 262.8577

3) Ferric Chloride -FeCl3
Molecular Mass= 159.6882

Hope it helps.
