The ammonia solution that is purchased for a stockroom has a molarity of 15 M. Determine the volume of 15 M NH3(aq) that must be diluted to 500 mL to prepare 1.46 M NH3(aq). Answer in units of mL.

The volume of stock solution of ammonia that is needed is 48.67 mL

Explanation:

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
