Question

1. using the graduated cylinder to the right, pick the accurate and precise measurement below. a. 22.0 ml b. 20.0 ml c. 22 ml d. 20 ml

Explanation:

Step1: Understand accuracy and precision

Accuracy refers to how close a measurement is to the true value. Precision refers to how close repeated measurements are to each other. In a graduated - cylinder, the more decimal places, the more precise the measurement. Also, we need to estimate to one - tenth of the smallest division on the graduated cylinder.

Step2: Analyze the options

Options C (22 mL) and D (20 mL) are less precise as they don't have a decimal place. Between A (22.0 mL) and B (20.0 mL), we assume based on the graduated - cylinder reading (not shown here but generally, we choose the value that is closest to the actual reading). If the reading is closer to 22.0 mL, then A is the answer. Since we are looking for accurate and precise, a measurement with one decimal place is more precise than one without a decimal place.

Answer:

A. 22.0 mL
