🤓 Based on our data, we think this question is relevant for Professor Cummings & Dillon & McCoy's class at FSU.
Given the mass percent of:
% Cl = 71.6%
Assuming we have 100 g of the compound:
The atomic masses are 12.01 g/mol C, 1.01 g/mol H, 35.45 g/mol Cl.
Dichloroethane, a compound that is often used for dry cleaning, contains carbon, hydrogen, and chlorine. It has a molar mass of 99 g/mol. Analysis of a sample shows that it contains 24.3% carbon and 4.1% hydrogen. What is its molecular formula?
