Here are the essential concepts you must grasp in order to answer the question correctly.
Molecular Weight Calculation
Molecular weight, or molar mass, is the sum of the atomic weights of all atoms in a molecule. It is calculated by multiplying the number of each type of atom by its atomic weight (from the periodic table) and summing these values. For example, in C8H6Cl2O3, you would calculate the contributions from carbon, hydrogen, chlorine, and oxygen to find the total molecular weight.

Chemical Formula Interpretation
A chemical formula provides information about the types and numbers of atoms in a molecule. In the formula C8H6Cl2O3, 'C' represents carbon, 'H' represents hydrogen, 'Cl' represents chlorine, and 'O' represents oxygen. The subscripts indicate the number of each atom present, which is essential for calculating the molecular weight accurately.

Periodic Table of Elements
The periodic table is a tabular arrangement of chemical elements, organized by atomic number, electron configuration, and recurring chemical properties. Each element has a unique atomic weight, which is crucial for calculating molecular weights. Understanding how to read the periodic table allows students to find the necessary atomic weights for elements in a compound, such as those in dicamba.
