The molecular mass of propanoic acid is 75.1 amu . Calculate the molecular mass of methyl ethanoate, an isomer of propanoic acid. Express your answer with the appropriate units.

75.1

Explanation:

The isomers contains the similar and accurate chemical formulas but at the same time the structure of the molecular is different. This represents that the masses of the molecular would be similar

Therefore the molecular mass of methyl ethanoate, i.e. an isomer propanoic acid is 75.1 i.e. equivalent to the molecular mass of the propanoic acid

So, it should be 75.1

Explanation:

The relation between average velocity of a gas molecules and its molecular mass is as follows .

average velocity v

where k is a constant .

If v₁ and v₂ be the velocities corresponding to molecular masses 349 and 352 .

= 1.004
