# Explanation:
## Step1: Find atomic counts per compound
Use subscripts to count atoms:
- $	ext{AgNO}_3$: $	ext{Ag}=1$, $	ext{N}=1$, $	ext{O}=3$
- $	ext{NiSO}_3$: $	ext{Ni}=1$, $	ext{S}=1$, $	ext{O}=3$
- $	ext{Ca}_3(	ext{PO}_4)_2$: $	ext{Ca}=3$, $	ext{P}=2$, $	ext{O}=8$
- $	ext{HgSO}_4$: $	ext{Hg}=1$, $	ext{S}=1$, $	ext{O}=4$
- $	ext{Fe(NO}_3	ext{)}_3$: $	ext{Fe}=1$, $	ext{N}=3$, $	ext{O}=9$
- $	ext{Co(ClO}_3	ext{)}_2$: $	ext{Co}=1$, $	ext{Cl}=2$, $	ext{O}=6$
- $	ext{Cu}_2	ext{C}_4	ext{H}_4	ext{O}_6$: $	ext{Cu}=2$, $	ext{C}=4$, $	ext{H}=4$, $	ext{O}=6$
- $	ext{ZnCl}_2$: $	ext{Zn}=1$, $	ext{Cl}=2$
- $	ext{K}_3	ext{PO}_4$: $	ext{K}=3$, $	ext{P}=1$, $	ext{O}=4$
- $	ext{Al}_2(	ext{SO}_4	ext{)}_3$: $	ext{Al}=2$, $	ext{S}=3$, $	ext{O}=12$
- $	ext{MgCrO}_4$: $	ext{Mg}=1$, $	ext{Cr}=1$, $	ext{O}=4$
- $	ext{CaC}_4	ext{H}_4	ext{O}_6$: $	ext{Ca}=1$, $	ext{C}=4$, $	ext{H}=4$, $	ext{O}=6$
- $	ext{NaCl}$: $	ext{Na}=1$, $	ext{Cl}=1$
- $	ext{K}_2	ext{Cr}_2	ext{O}_7$: $	ext{K}=2$, $	ext{Cr}=2$, $	ext{O}=7$
- $	ext{H}_2	ext{SO}_4$: $	ext{H}=2$, $	ext{S}=1$, $	ext{O}=4$
- $	ext{Cu(OH)}_2$: $	ext{Cu}=1$, $	ext{O}=2$, $	ext{H}=2$

## Step2: Get atomic masses (g/mol)
Use standard atomic masses:
$	ext{Ag}=107.87$, $	ext{N}=14.01$, $	ext{O}=16.00$, $	ext{Ni}=58.69$, $	ext{S}=32.07$, $	ext{Ca}=40.08$, $	ext{P}=30.97$, $	ext{Hg}=200.59$, $	ext{Fe}=55.85$, $	ext{Co}=58.93$, $	ext{Cl}=35.45$, $	ext{Cu}=63.55$, $	ext{C}=12.01$, $	ext{H}=1.008$, $	ext{Zn}=65.38$, $	ext{K}=39.10$, $	ext{Al}=26.98$, $	ext{Mg}=24.31$, $	ext{Cr}=52.00$, $	ext{Na}=22.99$

## Step3: Calculate total mass per element
Total = Atoms $	imes$ Atomic Mass
## Step4: Sum for molar mass
Molar mass = Sum of all element totals
