a. A student records the masses of three unknown samples to be 33.25 g, 43.265 g, and 25.1 g, respectively. What is the correct number of significant figures the student should use when recording the average?
b. A student measured an item and found that its mass is 0.010010 grams. How many zeros are significant figures in this measurement?
c. The first part of the experiment takes 32 seconds and the second part of the experiment takes 17.9 seconds. How long does the entire experiment take, using significant figures?
Oh, and i forgot to add, could you explain why the answer is what it is?
