c) Mg₃(PO₄)₂
Transcribed Image Text:**8. Calculate the formula weight and equivalent weight of the following:** a) BaCl₂·5H₂O b) NaHC₂O₄ c) Mg₃(PO₄)₂
Expert Solution
Step 1: Formula

Equivalent weight = formula weight/n-factor 

In case of salts,

n-factor = total positive or total negative charge

In case of acids, 

n-factor = number of replaceable H-atoms

In case of bases,  

n-factor = number of replaceable OH--atoms
