 Okay, so let's finish up this experiment. So we've been trying to find the density of this Irregularly shaped object so this big it from the chemistry sink, so you guys can see this metal piece we weighed it earlier And we got a mass of 41 point eight zero grams Of course, that's four significant figures right and then we did that volume displacement if you recall we dropped it in a graduated cylinder and then the water level rose in the graduated cylinder and then we Calculated what the actual volume of the object was so now let's go ahead and Finish up the last piece of experimental data So all we're going to do is figure out what the density is because that was the whole point of the experiment So the density of course remember equals mass divided by volume Okay, we've got the mass of their regularly shaped object. We've got the volume of it. So it's a simple Just plug-in chug right so 41 point eight zero Grams 5.1 cubic centimeters So this because we've got four sig figs two sig figs. This should be Two sig figs, right? Okay, so let's do this together 41 point eight zero divided by 5.1 equals 8.2 grams for cubic Okay, so that's how to figure out what the density of an irregularly shaped object is and Actually doing it in the laboratory. Okay, any questions on that stuff? Get pretty straight forward
