34.9 cL = 0.00349 hL is the answer!
Explanation:
An atom consists of electrons, protons, and neutron. The protons and neutrons are present inside the nucleus whereas the electrons are present outside the nucleus.
These electrons revolve around the nucleus in circular motion. Therefore, an electron pair surrounds the central atom of a molecule. It is known that an electron contains a negative charge and like charges repel each other.
Hence, in an atom the force of repulsion between electron pairs pulls the atoms away from each other.
As a result, a molecules atoms are as far away from each other as they can get.
Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol
