at a fixed temperature and pressure, a cylinder contains equal volumes of o2 and an unknown gas, weighing 20.0 g and 17.5 g resp
sukhopar [10]

At a fixed temperature and pressure, a cylinder contains equal volumes of O2 and an unknown gas. The identity of the unknown gas CO.

The number of moles of a given substance is calculated by dividing the mass by the molar mass.

The number of moles of O₂ = \mathbf{=\dfrac{20.0 \ g}{32 \ g/mol}}

= 0.625 moles.

Based on the given assumption, at fixed temperature and pressure;

  • Let assume that the number of moles of the unknown gas is = 0.625 moles  

The molar mass of the unknown gas can be estimated as:

\mathbf{= \dfrac{mass}{number \ of \ moles}}

\mathbf{= \dfrac{17.5 \ g}{0.625 \ moles}}

= 28 g/mol

Therefore, we can conclude that the unknown gas is CO.
