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

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
