The short answer is yes, gas has mass and density. However, you should note that gas is a state of matter, just as solid and liquid are. Since all matter has mass, any substance in its gaseous state has mass. Since all matter occupies space, it has density, since density is defined as mass per unit volume, where volume is space.

Larger objects dont always have more mass than smaller objects.

How do you measure the density of a gas?

To measure the density of a gas you find the mass and volume, then divide the volume by the mass.


How do you calculate density of gas?

density = mass/volume


Why does density increase when a gas is compressed?

There will be the same amount of gas but in a smaller space. Density is mass/volume So as volume decreases and mass is constant, the density increases.


What is the mass density of the oxygen gas?

Oxygen - Atomic Mass: 15.9994.


The molar mass of a gas can be determined from what the density of the gas at STP the volume of a mole of the gas Avogadro's number none of the above?

The density of the gas at STP.


What is the relationship between mass volume and density of solids liquids and gasses?

mass is mass for solid, liquid, and gas. density of solid > density of liquid > density of gas volume of solid < volume of liquid < volume of gas There are some exceptions to "density of solid > density of liquid" and "volume of solid < volume of liquid", with some of them being ice / water and rock / magma.


How does the density of water change when it moves from a liquid to a gas?

First of all, the density of water decreases when it gets in gas state. Density is depended on mass and volume and thus the formula density= mass/volume. When water gets into gas state, the volume increases which results in an decrease in density.


What will happen to the density of a gas if the mass if gas doubles and the volume of the gas is cut in half?

Density would go up 4 times


What happens to the mass density and volume of a rising gas bubble?

The mass remains the same.the volume increases.the density decreases.


What is the mass of a 20 L sample of gas with a density of 0.04 mgL?

Density is defined as mass / volume. Solving for mass: mass = density x volume In other words, all you have to do is multiply the density times the volume, to get the mass. Answer:0.8 mg

Why does the density stay if the mass increases?

The question cannot be answered because its basic assertion not true. If the mass of a gas in a closed container is increased, then the density of the gas WILL increase.


What is the specific gravity of gas?

Density = Mass/Volume The density of natural gas (CH4) is approx. 800 g/m3.


What is the relationship between Volume and mass for a gas?

for an gas,the relation PV=nRT holds good. n is no. of gas moles. Mass depends on density but density is directly proportional to pressure P.so at constant P,mass is given by VxDensity.


The molar mass of a gas can be determined from?

the density of the gas at STP (standard temperature and pressure)


Conditions for finding density of a gas?

Mass of the gas divided by the area it takes up.


The molar mass of a gas at STP is the density of that gas?

NO. Use the formula PV=nRT


What effects on density of air if tempecture increase?

A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.


Calculate the density of a sample of gas with a mass of 30g and a volume of 7500cm3?

density= mass/volume 30g/7500cm3=.004g/cm3


Does the volume of a gas change when the volume of the container it is in increases?

Volume = Mass/Density. In a larger container the mass of the gas remains unchanged, the density decreases so the volume increases.


How do you find mass and density of the gas cylinder?

That all depends on the type of gas and volume given for the problem. We can't determine the mass and density of the gas cylinder if we are not given these info, which can also include pressure (because density varies based on that variable).


How do you find the density of a solid?

Density = mass/volume for solid, liquid, or gas. It doesn't matter.


If the temperature of a gas in a movable piston is decreased what will happen to the density of the gas?

It will increase. Density is mass/volume. Mass remains constant since no matter is entering or escaping. Lowering the temperature decreases the volume. Same mass in a smaller space= increased density.


How does density of a gas change with rise of temperature?

The density depends only on the mass of the sample and the volume to which it is confined. Then the density is (mass) divided by (volume), regardless of what happens to the temperature, or why.
