Question

Give one example of a compound molecule in which molecular mass is twice of empirical mass.​

Answer 1

Answer:

) Write the empirical formula:

C

2

H

3

O

2) Compute the "empirical formula mass:" by taking the mass of each mole of the given element. One mole of Carbon has mass 12 g, Hydrogen has mass 1 g, and O has mass of 16 g.

2x 12 + 3x1 + 1x16 = 43g

3) Divide the molecular mass by the "Empirical formula mass:"

86.1 / 43 = 2 (approximately)

4) The molecular mass is twice of empirical formula mass , it means that the ratio of elements in molecular formula is twice the ratio of elements in empirical formula.

Answer 2

Explanation:

C2H3O is the example of a compound
