A chemist must prepare 0.200 L of aqueous silver nitrate working solution. He'll do this by pouring out some aqueous silver nitrate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in of the silver nitrate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

A chemist must prepare 0.200 L of 1.00 M aqueous silver nitrate working solution. He'll do this by pouring out 1.82 mol/L aqueous silver nitrate stock solution into a graduated cylinder and diluting it with distilled water. How many mL of the silver nitrate stock solution should the chemist pour out?

0.110 L

Explanation:

According to the dilution law,

where,  

= molarity of stock silver nitrate solution = 1.82 M

= volume of stock silver nitrate solution = ?  

= molarity of diluted silver nitrate solution = 1.00 M

= volume of diluted silver nitrate solution = 0.200 L

Putting in the values we get:

Therefore, volume of silver nitrate stock solution required is 0.110 L

a chemical reaction happens

explanation:

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
