You need to prepare 250.0 mL of a 1.35 M HCl solution from a 4.50 M HCl stock solution. Glassware A is a 250 m L beaker. Glassware B is a 250 m L erlenmeyer flask. Glassware C is a 250 m L volumetric flask. Assuming that the accuracy of the concentration is important, which type of glassware should you use to make the solution

Glassware C

Explanation:

According to moalrity equation:

= Molarity of stock solution = 4.50 M

= volume of stock solution = ?

= molaity of diluted solution = 1.35 M

= volume of diluted solution = 250.0 ml

A volumetric flask is more accurate for making solutions than a beaker or erlenmeyer flask and hence to measure 75.0 ml of stock solution , we use 250 ml  of volumetric flask.

Thus 75.0 ml of stock is pipetted out using pipette and put into a volumetric flask of 250 ml and water is added till the mark reaches 250 ml.

A volumetric flask is more accurate for making solutions than a beaker or erlenmeyer flask and hence to measure 75.0 ml of stock solution , we use 250 ml  of volumetric flask.
