Q Question 1 3 / 3 pts Complete the following statements by choosing either “accuracy” or “precision”: Accuracy refers to the comparison of a measurement in the lab to its actual, true value. When you can increase the number of significant figures in a lab measurement, you are in fact increasing the Precision of the measurement. Question 2 1 / 2 pts In the following two values that a Geology student has measured for the density of a rich mineral, some zeros are significant and others are not. How many significant figures are there in the following: Question 3 0 / 2 pts In our experiment today, you will obtain the volume of a metal cylinder in two different methods. One is by measuring its diameter and length, then applying a geometric formula, V = 1/4(?•D2•L). Can you describe the second method? Question 4 1 / 1 pts Density is an intensive property. It is physical property that does not depend on the amount of the substance. Question 5 2 / 2 pts What is the calculated density of a metal cylinder, reported by a scientist to the correct number of significant figures, if the weighing balance displayed a mass of 18.5665 grams, and the volume change observed after plunging it into a graduated cylinder with water is 7.68 milliliters?
