A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240 -g rock that displaces 89.0 $\mathrm{cm}^{3}$ of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes" principle.)

Then we had problem. 55. Similar problem 50 or 52. Similar problem 51. We have to find a master of the liquid first. 52. Yeah. Okay. Yeah. Okay. Okay. The problem. We have this. The answers have 5. 22.2. Nice. But keep in mind, not only do the same. All right. Here. So you have to get only 52 3. 30. Get rather number. Now, most of the time is very important when you door experiment and research. And here we have this equal the balloon. Okay. Okay. Okay. Had massive ego 52. Okay, okay. To bottom equal, do you think?

Yeah, Okay, so we have the two graduated cylinders. One of them has water up to this mark right here, the three ml. And so we know the accuracy to the ones place. We have three ml and then We have the other one which has a .03 so accurate to the hundreds place. So if you were to add these up, you'd get mathematically 3.3 but you're, the accuracy of your final answer is of a calculation is limited by the least accurate measurement, which in this case is the three millimeters to the ones place. So you have to round to the ones place and then you'll just get three millimeters. Mhm.

You guys live strip probably 1 24. In this problem, we need to draw a piece of lab glassware that can approximately measure the volume of liquid, which is the volume is given US 102.87 million. Leader to measure 32.7 million later liquid. We need to use our 15 religion graduated cylinder, and we can draw the picture of this 15 millimeters graduated cylinder. Make this way, and 32.7 million litres should be blessed here.

Here we have a graduated cylinder that we are asked to record the volume. Let me draw a picture of what is shown in the diagram And it appears that there's a meniscus somewhere between the 20 mil leader line and this line just below it. So we need to know whether or not the line below it is greater than or less than 20. We figure that out with the 10 down here, so volume is decreasing as we go down. So this must be 10, 11, 12, 13, 14, 15, 16, 17, 18, 19. So it's somewhere between 19 and 20. Each line represents one mil leader, So we know for certain it's between 20 and 19, so we can estimate the decimal place. I'm going to estimate that it is 19.5 ml. You might estimate 19.4 19.6. But somewhere in this region where the uncertainty is in the first decimal place.
