Gas Y effuses through a pinhole 1.5 times as fast as $S O_{2}$ under the same conditions. Find the molar mass of Y in g/mol, correct to two decimal places.

Answer:

28.44

Solution:

Graham's law: r(Y)/r( $S O_{2}$ ) = $M (S O_{2}$ / $M$ (Y)) = 1.5.

64/ $M$ (Y) = 2.25, so $M$ (Y) = 64/2.25 = 28.44 g/mol.

Answer: 28.44.
