Question

A silver nitrate (AgNO3) solution is 0.150 M. 100.0 mL of a diluted silver nitrate solution is prepared using 10.0 mL of the more concentrated solution (which is then diluted with distilled water to 100.0 mL). Use the dilution equation to find the molarity of silver nitrate in the diluted solution.

Answer 1

Answer: The molarity of silver nitrate in the diluted solution is 0.015 M

Step-by-step explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the dilution law,

`M_1V_1=M_2V_2`

where,

`M_1` = molarity of concentrated solution = 0.150 M

`V_1` = volume of concentrated solution = 10.0 ml

`M_2` = molarity of diluted solution = ?

`V_2` = volume of diluted solution = 100.0 ml

`0.150* 10.0=M_2* 100.0`

`M_2=0.015M`

Thus the molarity of silver nitrate in the diluted solution is 0.015 M
