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?
Answer: 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
Answer:
The percent yield is 66.7%
Explanation:
1. The balanced chemical reaction to obtain carbon dioxide from the methane is:
2. Calculathe the theoretical quantity of carbon dioxide.
As the problem says that the limiting reagent is the methane, all the calculations will be made from this quantity:
3. Calculate the percent yield:
Percent yield =
Percent yield =
Percent yield = 66.7%
