A chemist was tasked with removing 50mL from a 2.5L stock solution of hydrochloric acid. After completing the task, it was discovered that 2.45L of the stock solution remained. What was the chemist's percent error?

Answer 1

Answer:

0%

Step-by-step explanation:

The chemist was tasked with removing 50mL from a stock solution of HCl acid.

Now:

• 1 Litre =1000 mL
• Volume to be removed=50mL=(50/1000)=0.05L

After the task, it was discovered that 2.45L of the stock solution remained.

• Volume removed=2.5L-2.45L=0.05L

Since the volume of acid removed by the chemist is equal to the volume of what the stock solution was reduced by, his percentage error is 0%.
