# How do you add density and volume to equal mass?

You cannot add those two quantities; they are not compatible because they have different units. Think of it this way: you can't add apples and oranges to get apples (or oranges), and you can't add 2x and 3y to get 5x (or 5y), so you can't add kilograms per cubic meter and cubic meters to get kg/m3 or m3. But you CAN multiply them! If you multiply a volume of a substance by its density, you will know how much of that substance you have. For example, if you have ten gallons of water and know that water's density is 8.34 pounds per gallon, then you know you have ten times 8.34, or 83.4 pounds of water. If you have 150 milliliters of liquid mercury and know that mercury's density is 13.6 grams per milliliter, you can multiply 150 by 13.6 to get 2040 grams (2.04 kilograms). Note that you must have compatible units. If the volume is in fluid ounces but the density is in grams per cubic centimeter, you will have to convert one of them (or perhaps BOTH of them) so that they are compatible and can be multiplied.

### Does flattening a block affect mass volume and density?

It will not affect mass because the mass of an object stays the same (unless you take away or add mass). It will affect volume and density. Since the object is being flattened so it takes up less space, its volume is smaller. But since it is the same amount of matter just in a smaller space, the density is greater. Basically, volume and density are inversely related (in respect to mass). With mass staying…

### Is the volume of an object directly related to it's density?

Volume is not directly related to the density - but it is related. Density is defined as mass/volume. You can add more mass of the same density and increase volume - 2 gallons of water will have more volume than 1 gallon but the density stays the same. On the other hand, if you keep the mass the same and change the volume, the density will change as well; compressing 5 liters of air into…

### How can we calculate the density of a irregular solid or a liquid?

You can dip the irregular solid in a water or other suitable liquid. This is how, you can measure the volume of the solid. The mass can be measured by weighing scale. Mass/volume = density. It is easy to measure the mass and volume of the liquid. First measure the mass the container. Then add the liquid to it. You will get the mass of the liquid. Then measure the volume of the liquid. Use…

### Why does density of a substance not change if you have more of that substance?

Density is equal to the mass per unit of volume. So if you add more of that substance, you are increasing both the volume, and mass of the substance. For example let's say I have 1kg of a substance which just do happens to fill 1L of a container. This means the density of the substance is 1/1 which is 1. Now if I increase the mass to 2kg, the volume will also increase because…

### What is the density of a metal cube with a mass of 64 g.?

Depends what metal. If I might add to the above, you cannot calculate the density of a substance without knowing its mass (weight) and its volume, since density is mass per unit volume. On the other hand, if you know the type of metal, and that it is pure, you can simply look up the density in a table since the density of all substances is constant for that substance, regardless of the weight or…

### Will a boiled egg float if you add salt to water?

Yes, it will eventually. When you add salt to water, you are increasing the density of the solution, but not the volume, because the salt dissolves (dissociates). Since density is mass divided by volume, there is a direct relationship between the solution's mass and its density. They increase together even as the volume remains constant. An egg will float in a salt solultion if the molarity is about 2.5 or above.

### Why does adding salt to water increase its density?

Density is the mass per unit volume. Therefore, adding salt increases the mass of the water by a larger scale than it does the volume of the water. Actually when you add salt to the same volume of water the mas of the water has a noticeable increase, where as the volume appears to the same ( the volume does increase; however the change is so small that it is unnoticeable ,thus we say it…

### Will air bubbles affect the volume when measuring the volume of a metal.?

Air bubbles would make the volume you read in the measuring cylinder increase from the actual volume of theliquid. so when you add in the metal, there would be an increase in the volume of the metal than it really is. the mass of the metal cannot be affected by air bubble because this is the amount of matter in the metal. This increase in volume causes the density of the metal to reduce from…

### How would you measure the mass of an orange?

Put it on a scale. Put it on a balance and put weights of known mass on the other side until it is even. Put the orange in a container of known volume, add water until the container is filled subtract the amount of water added from the container and get the volume of the orange (or measure the orange and compute the volume) guess that the orange has a density of almost exactly 1…
