Question

Question 12 of 22 You need to prepare 250.0 mL of a 1.05 M HCI solution from a 5.00 M HCI stock solution. Which type of glassware should you use to make the solution (assuming that the accuracy of the concentration is important)? Map o How should the correct amount of stock solution be obtained? 200 m O Measure out x mL using a graduated cylinder. O Measure out x mL using a volumetric pipet O Measure out x g on a balance. 150 100 Based on your answer above, what is the value of x? Number continued below... How should the solution be mixed together? Fill the container to the 250 mL mark then add the correct amount of stock solution. Add the correct amount of stock solution then fill to the 250 ml mark with water. Fill the container partially with water, add the correct amount of stock solution, then fill to the 250 O ml mark with water O None of these are the correct way to mix the stock solution. Next Exit Hint

Explanation / Answer

1) Volume of 5 M HCl solution required to make 250 ml of 1.05 M solution , V = 1.05*250/5 = 52.5 ml

52.5 ml can best be measured using pipette

Hence the correct option is :- (B)

2) x = 52.5 ml

3) The correct option is :- (B)
