Concept Of Mole MDCAT Quiz of chemistry, the understanding of which is central to the understanding of the quantitative nature of chemical reactions. In particular, for an MDCAT student, this subtopic is crucial in the sense that it forms the very basis for the solving of problems of stoichiometry, molar mass, and chemical equations. A mole represents a standard amount of matter and bridges the microscopic world of atoms and molecules with amounts that are easily measurable in a laboratory. This topic, being an extremely frequently asked one in the MDCAT Quiz, therefore becomes quite crucial for the student to understand the concepts clearly and in detail.
