A sample of certain mass of a gas was collected and it was fond that the number of atoms and the number of molecules in the collected sample are equal.from this observation infer the type of molecules of gas.

likely a noble gas, since the others form molecules of more than one atom.

To infer the type of molecules of the gas based on the given observation, we need to understand the relationship between atoms and molecules in different types of gases.

In a gas, atoms can either be elemental gases composed of individual atoms (like helium, neon) or molecular gases composed of molecules (like oxygen, nitrogen). The molecular gases consist of two or more atoms bonded together.

If the number of atoms and molecules in the collected sample is found to be equal, it suggests that each molecule in the gas is made up of only one atom. In other words, the gas consists of elemental gases composed of individual atoms.

Therefore, based on the observation that the number of atoms and molecules in the collected sample are equal, we can infer that the gas is an elemental gas made up of individual atoms.
