No. At STP, one mole of any gas is one 22.4L of that gas. However, because different gases are made up of different elements, the mass of one mole will differ depending on the gas. For example, one mole (22.4L) of hydrogen gas (H2) has a mass of 2.015888g, whereas, one mole (22.4L) of oxygen gas (O2) has a mass of 31.9988g.

What evidence supports avogadros hypothesis?
PV/NrT, pressure(volume)/amount(constant)(temperature). When your temperature, volume, and pressure are all the same, you get the same number of particles. This is avogadros hypothesis. Let's say that you have to balloons. They have the same temperature, volume, and pressure. If you weigh the gases in the balloon, you will find that there is the same amount of particles. In fact Dalton did this was able to find out the amount of particles (atoms) by the mass of objects.
How does the can crushing lab experiment demonstrate the principles of pressure and volume in gases?
The can crushing lab experiment demonstrates the principles of pressure and volume in gases by showing how changes in pressure can affect the volume of a gas. When the can is heated and then quickly cooled, the pressure inside the can decreases rapidly, causing the volume of the gas inside to decrease as well. This demonstrates the inverse relationship between pressure and volume in gases, known as Boyle's Law.
What are the differences between solids and liquids and gases?
the differences in these three items is that solid atoms are tightly compacted together liquid atoms are freely put move at a slow rate, then the gases atoms a freely just like the liquid atoms but the gases atoms move at a faster rate
Avogadro's principle canbe applied when these 3 measurements are the same?
Avogadro's principle can be applied when the temperature, pressure, and volume of a gas are the same. This principle states that equal volumes of gases at the same temperature and pressure contain the same number of molecules, allowing for the comparison of different gases under these conditions.
What are the key findings from the Boyle's Law pressure-volume relationship in gases lab?
The key findings from the Boyle's Law pressure-volume relationship in gases lab are that the pressure of a gas is inversely proportional to its volume when the temperature is constant. This means that as the volume of a gas decreases, its pressure increases, and vice versa. This relationship can be described by the equation P1V1 P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
What volume of nitrous oxide gas has the same number of atoms as 9.00L od neon gas at same temperature and pressure?
Since both gases are at the same temperature and pressure, they have the same number of moles. Nitrous oxide (N2O) has 3 atoms in a molecule, while neon (Ne) is a monoatomic gas. Therefore, 9.00L of neon gas would have the same number of atoms as 3 times the volume of nitrous oxide gas, so the volume of nitrous oxide gas needed would be 3.00L.

What effects pressure?
Pressure can affect the physical properties of gases, liquids, and solids. For gases, pressure influences volume and temperature through the ideal gas law. In liquids, pressure can impact density and boiling point. In solids, pressure can cause compression or expansion, altering the arrangement of atoms and thus changing the material's properties.
Why is the pressure higer in cold air than warm air?
The gases air consists of are roughly described by the formula pV=nRT, where p is pressure, V is volume, n is the number of molecules/atoms, R is the gas constant and T is temperature. As the temperature rises, so will the pressure.
What is avagadro's law in science?
The volume of ideal gases, at the same temperature and pressure, have the same number of particles/molecule.

Why does gas pressure?
Gas release pressure because gases are made of atoms.
How does the changes in temperature and pressure affect the volume and the amount of gases?
In general chemistry we are taught the ideal gas equation of state PV=nRT. n is the number of moles of gas and R is the molar gas constant. This is an extremely important equation in the study of thermodynamics.

What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
Is the pressure exerted by different gases different?
Yes, the pressure exerted by different gases can be different, as it depends on factors such as the number of gas molecules, temperature, and volume. However, if the gases are in the same container at the same temperature, they will exert the same pressure.
