Question

which of the following measurements was recorded correctly from a graduated cylinder marked with one - milliliter increments? 12.3 ml 10 ml 15 ml 11.55 ml

Explanation:

Step1: Recall significant figures for graduated cylinder

A graduated cylinder with 1 - mL increments can be read to the tenths place (one decimal place) because we estimate one digit beyond the smallest marked increment.

Step2: Analyze each option

• 10 mL: This has no decimal places. It doesn't estimate the tenths place, so it's not precise enough.
• 15 mL: Also has no decimal places, same issue as above.
• 11.55 mL: This is to the hundredths place, but with 1 - mL increments, we can only estimate to the tenths place (one decimal place), so this is too precise.
• 12.3 mL: This is to the tenths place, which is appropriate for a graduated cylinder with 1 - mL increments (we can estimate the first decimal place).

Answer:

12.3 mL
