The concentration of the silver nitrate solution is 1.86 moles/dm³ .
The concentration of a substance is the quantity of solute present in a given quantity of solution.
2AgNO₃(aq)+Ca(s)→Ca(NO₃)₂(aq)+2Ag(s)
0.201 g of Silver = 0.201/107.8 = 0.00186 moles
From the equation we can see that for 2 moles of Silver to form we need 2 moles of silver nitrate .
For 0.00186 moles we will need 0.00186 moles of Silver nitrate
The concentration of the solution can be determined as
Molarity = moles / L of solution = 0.00186 moles/l
or 0.00186 moles/cu.cm = 1.86 moles/dm³
Therefore the concentration of the silver nitrate solution is 1.86 moles/dm³ .
