How many significant figures can be recorded in the measure of the fluid and the graduated cylinder?
A 100 mL graduated cylinder is graded in divisions of 1 mL giving results which have 2 significant figures. Cylinders for measuring up to 10 mL to have divisions at 0.1 mL, so again giving 2 sig figs.2 digits. .

What is number of digits in a measurement that you know with a certain degree of reliability?
The number of digits in a measurement that you know with a certain degree of reliability is referred to as significant figures. Significant figures include all the known digits in a measurement plus one estimated digit, indicating the precision of the measurement. For example, if a measurement is recorded as 12.3, it has three significant figures, reflecting a reliable accuracy up to the tenths place. The more significant figures, the greater the confidence in the accuracy of the measurement.
What is the measurement recorded in percentages?
A percentage is a pure number: it has no measurement units.

A water sample has a volume of exactly 12.0000mL How would this volume be recorded if it were measured from a a 50-mL graduated cylinder?
The volume of 12.0000 mL would be recorded as 12.00 mL when measured from a 50-mL graduated cylinder because the cylinder has markings in increments of 1 mL. It is standard practice to record the volume to two decimal places for greater accuracy.

How do you explain significant figures are related to precision and accuracy?
Significant figures indicate the precision of a measurement, representing the certainty of the digits recorded. The more significant figures a number has, the more precise it is, as it reflects a finer level of detail in the measurement. Accuracy, on the other hand, refers to how close a measured value is to the true value. While significant figures convey precision, they do not guarantee accuracy; a precise measurement can still be inaccurate if systematic errors are present.

How many significant figures can be recorded on the time of a stop watch?
The number of significant figures that can be recorded on a stopwatch typically depends on the resolution of the stopwatch itself. For most digital stopwatches, the time can be recorded to the nearest hundredth of a second, allowing for three significant figures (e.g., 12.34 seconds). Analog stopwatches may vary, but they often provide two significant figures (e.g., 12.3 seconds) depending on the precision of the measurement. Ultimately, the precision of the stopwatch dictates the number of significant figures that can be reported.
