What else can I help you with?
At a certain temperature and pressure 0.02 mol of carbon dioxide has a volume of 3.1 L A 3.1 L sample of hydrogen at the same temperature and pressure?
contains the same number of molecules
A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
Which closed cylinder contains the same number of gas molecules at STP as a 4.0 liter closed cylinder containing O2 gas at STP?
ANY closed cylinder of 4.0 litre will contain the same number of molecules of ANY gas as the 4.0 liter closed cylinder containing O2 gas at the SAME temperature and pressure, since then the volume only depends on the number of molecules, not on the kind of molecules of the gasses concerned
Which gas contains the same number of molecules as 9 g of water?
9 g of water contains approximately 3.01 x 10^23 molecules. The gas that contains the same number of molecules as 9 g of water is Avogadro's gas constant, which is about 22.4 liters per mole at standard temperature and pressure.
What does Avogadro's principle state?
Avogadro's principle states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. This principle is the foundation for the concept of the mole in chemistry, where one mole of any gas at standard temperature and pressure occupies a volume of 22.4 liters.

Does one ml have the same density of 15 liters?
Any sample of the same substance has the same density,no matter how large or small the sample is.
Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
The gas particles in both flask A and B will have the same average kinetic energy at the same temperature. This is because temperature is a measure of the average kinetic energy of the gas particles, and since they are at the same temperature, their average kinetic energies will be equal.
Why are there always the same number of adenine and thymine in a molecule?
Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
A sample of an element consists of the same type of atom. What does a sample of a compound consist of?
Identical molecules.
Is a compound same through out?
A sample of a pure compound consists of the same molecules throughout its mass.
Which closed cylinder contains the same number of gas molecules at STP as a 4.0 liter closed cylinder containing O2 gas at STP?
ANY closed cylinder of 4.0 litre will contain the same number of molecules of ANY gas as the 4.0 liter closed cylinder containing O2 gas at the SAME temperature and pressure, since then the volume only depends on the number of molecules, not on the kind of molecules of the gasses concerned
How many types of molecules with different masses exist in a sample of chlorine gas if the same exists entirely as diatomic molecules?
In a sample of chlorine gas, all molecules are diatomic composed of two chlorine atoms. This means there is only one type of molecule in the sample, with a molecular formula Cl2.
Do molecules have the same number of protons?
No
In a sample of pure copper all atoms have the same what?
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
Which gas contains the same number of molecules as 9 g of water?
9 g of water contains approximately 3.01 x 10^23 molecules. The gas that contains the same number of molecules as 9 g of water is Avogadro's gas constant, which is about 22.4 liters per mole at standard temperature and pressure.
