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 C15H22ClNO2, you would calculate the contributions from carbon, hydrogen, chlorine, nitrogen, 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 C15H22ClNO2, 'C' represents carbon atoms, 'H' represents hydrogen, 'Cl' is chlorine, 'N' is nitrogen, and 'O' is 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 elements, organized by increasing atomic number and grouped by similar 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 atomic weights needed for the molecular weight calculation of compounds like metolachlor.
