Masses are the same because they are balanced evenly.

Answer:

C The molar mass of substance B is greater than substance A

Step-by-step explanation:

From the description given, the molar mass of substance B is definitely greater than that of substance A.

Temperature increases the kinetic energy of a body. The average molecular speed increases with increasing temperature.

Since the two bodies given are at the same temperature, the one having a lesser molecular mass will have a higher speed.

Substances with low molecular mass can diffuse or effuse more rapidly than one with higher molecular mass under similar conditions.
