In summary, at the same temperature and pressure, equal volumes of different ideal gases must contain the same amount of gas, or the same number of atoms. This is because the molar ratios of the gases are equal, regardless of the number of atoms in each molecule. Therefore, choice A and C are both correct.

"Equal volumes of different ideal gases at the same temperature and pressure must contain:"

A. The same number of atoms
B. one mole of each gas
C. The same amount of gas
D. 6.022 x 10^23 particles of each gas


Since it is not 24dm^3 of each gas, I can rule out B and D.

After rearranging the gas equation:

NRT/P = NRT/P

N = N

The molar ratios are equal, but i don't know which of A or C is correct since i don't see the difference.

helium molecule contain one atom, hydrogen molecule contain two atom...
and the N in your equation represent number of molecule...
so the answer is...

Related to Equal Volumes Ideal Gases: Same Temp, Pressure- A or C?

1. What is an equal volumes ideal gas?

An equal volumes ideal gas is a theoretical gas that follows the ideal gas law, which states that at a constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of the gas present.

2. Why are the temperatures and pressures the same in this scenario?

In an equal volumes ideal gas scenario, the temperatures and pressures are the same because the gases are contained in identical volumes and are at the same temperature. This means that the molecules of the gases have the same amount of kinetic energy and are colliding with the walls of the container at the same rate, resulting in the same pressure.

3. How does this relate to the kinetic theory of gases?

The kinetic theory of gases explains the behavior of gases in terms of the motion of their particles. In an equal volumes ideal gas scenario, the gases are at the same temperature and pressure, meaning that their particles have the same average kinetic energy and are moving at the same speed.

4. What is the significance of equal volumes ideal gases in scientific research?

Equal volumes ideal gases are important in scientific research because they provide a theoretical framework for understanding and predicting the behavior of gases. This can be useful in a wide range of fields, including chemistry, physics, and engineering.

5. How does the ideal gas law apply to equal volumes ideal gases?

The ideal gas law, which states that PV = nRT (where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature), applies to equal volumes ideal gases because the volume of a gas is directly proportional to the number of moles of the gas present at a constant temperature and pressure.
