Calculate the density of a piece of metal if
its mass is 201.0 $\mathrm{g}$ and its volume is 18.9 $\mathrm{cm}^{3} .$

So we have a unknown metal that has a massive 50 for grants and the dimensions are one by two by 10 centimetres. Uh Which if you were to find the volume, you just need to multiply the length times, weight, times height, one times two times 10 is equal to 20 and that's going to be in cubic centimeters. So if we want to find the density, we we just take the mass divided by the volume 54.0 g, divided by 20 cubic centimeters gives us a density of 2.7 g per cubic centimeter. We can use this to identify the stamp what the sample is because each substance has a unique density. It's an intensive property. So, um, when we look at our table of densities, we'll see that 2.7 corresponds to the metal aluminum A. L. And that is are unknown.

This question is in reference to the concept of density. Density is a property of a substance that describes the amount of the substance in grams per the volume of the substance, often in units of centimeters, cube or milliliters. So if we want to calculate the density of this metal object, we need to know its mass, which was given to us at 252 g and its volume, which was given to us at 30.0 centimeters. Cube. When we divide these two numbers, we get a density of 8.40 g per centimeter cubed using density, we could potentially identify what this medal is. This metal could be any metal that has a density close to 8.40 So if you were to review a table of the density of metals, you could find one that has a density close to 84. In this case, it could be brass

Calculate the density of the metal or we need to do is take the mass divided by the volume, and we'll get a density of 8.4 grams per centimeter. Cubed. The metal could, uh, potentially be any metal that has a density or mixture of metals in the alloy, close to a density of 8.4 grams per centimeter cube. And it turns out that brass has a density pretty close to 8.4, so potentially the piece of metal could be brass.

For this question, you're simply asked to calculate the density of a substance knowing it's measured mass and information to calculate its measured volume density is simply equal to the mass of an object in grams divided by its volume in millilitres. The mass of the object in grams is provided. It is 37.51 g. You are then told that the object is placed into a graduated cylinder And that the liquid level is increased from 50 ml to 50.75 million liters. The increase in the volume of the liquid corresponds exactly to the volume of the object placed into the liquid. So we can calculate the volume of the object by taking the difference in the volumes of the liquid. The volume of the object is then 7.5 ml. So to calculate density will take the mass 37.51 g, divided by the volume 7.5 mL. And we get 5.0 g per mil leader as the density.
