Question

polyethylene is 86.0% c and 14.0% h. determine the empirical formula of the compound. percent to mass: how many grams of c and h are present in 100.0 g? 12.0 g and 1.00 g 86.0 g c and 14.0 g h 14.0 g c and 86.0 g h

Explanation:

Step1: Calculate mass of C and H

Given total mass = 100.0 g.
Mass of C = \(86.0\%\text{ of }100.0\ g=0.86\times100.0\ g = 86.0\ g\)
Mass of H = \(14.0\%\text{ of }100.0\ g=0.14\times100.0\ g = 14.0\ g\)

Answer:

86.0 g C and 14.0 g H
