Chapter 1, Problem 78A

To determine

The precise measurement that one can make with the given instrument.

Answer to Problem 78A

  $\text{0}\text{.5}\text{mL}$

Explanation of Solution

Introduction:

The precision of a number depends on the measurement up to as many decimal places.

To calculate the precision of the graduated cylinder, divide the smallest scale increment by 2.

In this case, the smallest scale division is $\text{1}\text{mL}$

Therefore, the precision in the measurement would be of:

  $\Delta V=\frac{\text{1mL}}{\text{2}}$

  $\Delta V=0.5\text{mL}$

Conclusion:

The precise measurement that one can make with the given instrument is $\text{0}\text{.5}\text{mL}$ .
