## The density of a gas is 0.90 g/l at stp. what is the gas

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As a result, one of the four basic states of matter is liquid (the others being solid, gas and plasma). A liquid is made up of small vibrating matter particles, such as atoms, that are held together by intermolecular bonds. Water is, by far, the most popular substance on Earth. A liquid, like a gas, can flow and take the form of a container. While most liquids are resistant to compression, some may be compressed. A liquid, unlike a gas, does not spread to fill all of the spaces in a container and retains a relatively constant density. Surface tension is a characteristic of the liquid state that causes wetting phenomena.
A liquid is a state of matter in which a material can easily change shape and take on the shape of its container while maintaining a constant volume regardless of pressure. As a consequence of this, a liquid does not hold a definite form, and its volume is variable. Surface friction, viscosity, and capillarity are all characteristics of liquids.

## Which of the following samples has the greatest density at stp no2 xe so2 sf6

Many people start working on their yards and homes when the weather is nice. Sand is needed for many projects as a walk base or to supplement other materials. You could order twenty million grains of sand and get a lot of attention. You could order by the pound, but weighing out takes a long time. Ordering by the yard, or cubic yard, is the safest option. The loader will quickly pick up what you require and load it into your vehicle.
It certainly is quick to count bananas or to count elephants (as long as you stay out of their way) (as long as you stay out of their way). You will, however, spend a long time counting sugar grains from your sugar canister. Atoms and molecules are incredibly tiny – much smaller than sugar grains. Counting atoms or molecules is not only dangerous, but also impractical. A drop of water contains approximately 10 22 water molecules. Just 1.6 10 10 molecules would have been counted if you counted 10 molecules per second for 50 years without stopping. To put it another way, counting the water molecules in a single tiny drop would take over 30 trillion years at that rate.

If the mole fraction of H2 is 0.350 and the pressure of H2 is 0.480 atm, what is the overall pressure of the mixture?

### Which of the gas samples in the graph below has the largest temperature

We expect a gas to rise into the air when we run a reaction to create it. Many students have conducted studies involving the formation of gases such as hydrogen. A test tube placed upside-down over the reaction will trap the gas. When carbon dioxide is emitted, on the other hand, it sinks. Because carbon dioxide has a higher density than air, it will not rise like hydrogen gas.
As you may know, density is defined as a substance’s mass per unit volume. Since all gases have the same volume per mole, the density of a given gas is determined by its molar mass. The density of a gas with a small molar mass is lower than that of a gas with a large molar mass. Gas densities are usually measured in $$\text{g/L}$$. Molar mass and molar volume can be used to measure gas density.
