Problem: Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical formulas. Calculate the empirical formulas of the following polymers:(a) Lucite (Plexiglas); 59.9% C, 8.06% H, 32.0% O

FREE Expert Solution

We’re being asked to determine the empirical formula of Lucite (Plexiglas) given the following percentages: 59.9% C, 8.06% H, 32.0% O


Recall that the empirical formula is the simplest whole-number ratio formula of a compound


For this problem, we need to do the following steps:

Step 1: Calculate the mass and moles of C, H, and O in the compound.

Step 2: Determine the lowest whole number ratio of C, H, and O to get the empirical formula.
