====﻿Significant figures are the numerical value of a laboratory measurement. In order for the measurement to be recorded properly you must use significant figures. For an example if you were using a 25mL cylinder, it would be necessary to have at least three significant figures. It would be necessary to have at least three, because the minor division is .5. You would do this because you would always have a number to fill the places. In measurements, you also have accuracy & precision. Accuracy shows how close the measurement is to the true and exact value. Precision shows how close several measurements are when measuring the same thing. For a 25mL you would need three significant figures, because you miner is .5, and you always have a number in its place.give or take. the smaller the uncertainty the greater the precision.====
