If a molecule of C 2 H 4 O diffuses a distance of0.830 m from a point source in

Question

If a molecule of C2H4O diffuses a distance of0.830 m from a point source in 17.1 s, calculate the rate (m/s)that a molecule of C3H6 would diffuse at thesame temperature and under the same conditions.

Molar Mass (g/mol) C2H4O 44.053 C3H6 42.081

Assuming it is part of a sample that behaves as an ideal gas,calculate the root mean square speed of a molecule ofCl2 that has the average translational kinetic energy of1.50E-20 J/molecule.

Molar Mass (g/mol) Cl2 70.905 Gas Constant (J/Mol K) R 8.31451 Avogadro's No(mol-1) 6.022x1023


C2H4O 44.053 C3H6 42.081

Explanation / Answer

(Diffusion of C2H4O) / (Diffusion of C3H6)  = Molar mass C3H6 /   molarmass C2H4O Diffusion of C2H4O = 0.830 m / 17.1 s = 0.0485 m/s 0.0485 / Diffusion of C3H6 = 42.081 / 44.053 So diffusion of C3H6 = 0.0496 m/s
