<u>Answer:</u> The volume of stock solution of ammonia that is needed is 48.67 mL
<u>Explanation:</u>
To calculate the volume of stock solution, we use the equation:
where,
are the molarity and volume of the stock ammonia solution
are the molarity and volume of diluted ammonia solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of ammonia that is needed is 48.67 mL
