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.
Yes, solids, liquids, and gases have different masses because their particles are packed differently. In general, solids have the most mass because their particles are closely packed, while gases have the least mass because their particles are spread out. Liquids have a mass between that of solids and gases.
Matter is the substance that has mass and takes up space. It can exist in various forms such as solids, liquids, and gases.
Assuming they are at the same temperature, ammonia will effuse most rapidly due to its lower molar mass compared to the other three gases. Effusion rate is inversely proportional to the square root of molar mass.
No, lighter gases effuse faster than heavier gases. This is because the rate of effusion is inversely proportional to the square root of the molar mass of the gas. Lighter gases have lower molar masses, which results in faster effusion speeds.
Hydrogen would effuse the fastest because it has the lowest molar mass among the gases mentioned. Effusion rate is inversely proportional to the square root of molar mass, so lighter gases effuse faster.
no, if you are talking about let's say, car gasoline, yes of course they have mass. But if you are talking about air gases. hydrogen, helium, etc. no. those types of gases do not have mass or take up space!
gases with the higher molar mass
Gases
Gases
Yes, gases have mass because they consist of individual particles (atoms or molecules) that have their own mass. The mass of a gas is determined by the combined mass of its individual particles.
Yes, it is true.
Yes, solids, liquids, and gases have different masses because their particles are packed differently. In general, solids have the most mass because their particles are closely packed, while gases have the least mass because their particles are spread out. Liquids have a mass between that of solids and gases.
The mass of the paper will decrease as it burns due to the conversion of paper into gases, soot, and ash. The total mass of the system (paper + jar) will remain the same, as the mass of the ashes, gases, and soot will equal the original mass of the paper.
Yes. Gases are still comprised of atoms, each of which contributes mass.
examples of where gases don't seem to have mass
Because it's a mixture of gases.
Yes. Anything with mass is matter.
