Question

Using the empirical formula, calculate the formula weight of the compound. Use the periodic table to help you.

Type the correct answer in the box. Round your answer to three decimal places.

Answer 1

The formula weight of the compound is

46.069 g/mol.

Step-by-step explanation:

Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:

molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.
