Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
How many milliliters in 650 milligrams?
That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.That depends on the density of the substance.

Which substance would have a mass of 135 g when it has a volume of 50 cm3?
Any substance with a density of 2.7 grams per cm3. Aluminium and Al alloys have a density of around 2.7 gcm-3
What is the density of an unknown substance with a mass of 16.5 g and a volume of 2.2 cm3?
Density = Mass/Volume = 16.5 g / 2.2 cm3 = 7.5 g/cm3
How many litters in a gram?
liter is a unit of volume, gram is a unit of mass, the two are not interchangeable. However if you want to know about a specific substance you need to know the substance's density to relate these two terms. Density= mass/ volume
How does the volume and density of a substance change when it is heated?
When a substance is heated, its volume generally increases due to thermal expansion. On the other hand, the density of the substance usually decreases since the same amount of matter now occupies a greater volume.
When a balloon is heated its volume doubles and what happens to its density?
It is reduced by haft
What happens to the density when heat is added?
When heat is added to a substance, it increases the kinetic energy of its particles, causing them to move faster and spread out. This leads to an increase in volume and a decrease in density since density is mass divided by volume.
What happens to the density of a given substance if you increase the amount of the substance that you have?
Nothing happens if the volume is also allowed to increase.
What happens to density when you keep the volume the same and increase the mass of the substance?
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.
When a balloon is heated its volume is doubled what happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
What happens to the density of the substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
When a Balloon is heated it's volume doubles . What happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
When a balloon is heated it's volume doubles what happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
When you divide the mass of a substance by its volume you get its what?
You get its density. Density is a measure of how much mass is contained within a specific volume of a substance.
How do you calculate the density of a substance?
The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.
Does the volume of an object change if heated?
The volume of a substance increases when heated
