Acompound analyzed as 18.0% carbon, 2.26% hydrogen, and 79.7% chlorine. calculate the empirical formula of the compound.

To answer this item, our basis is 100g. We solve for the masses of the given elements in this item,
 
            carbon:     (0.18)(100 g) = 18 g
            hydrogen:  (0.0226)(100 g) = 2.26 g
            chlorine:    (0.797)(100 g) = 17.7 g

Then, we calculate for the number of moles by dividing the masses by the molar masses of the given elements.

Number of moles:

              carbon = (18 g) x (1 mol / 12 g) = 1.5 moles
             hydrogen = (2.26 g) x (1 mol/ 1.01 g) = 2.23 moles
             chlorine = (79.7 g) x (1 mol / 35.45 g) = 2.25 moles

We get the ratio of the number of moles by dividing them with the lowest value, 1.5.
                      Carbon = 1.5 moles / 1.5 = 1
                      Hydrogen = 2.23 moles / 1.5 = 1.48
                      Chlorine = 2.25 / 1.5 = 1.5

The empirical formula is,
                     C1H1.5CL1.5
Simplifying,
                    C2H3Cl3

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. this makes plastics which are important also to people but sometimes it lead to harmful environmental effects such as global warming if these plastics are burned.
