6,172 Views

Here you will be able to find the 1st Year Chemistry Chapter 1 Fundamental Concepts MCQs with Answers. The first chapter is the fundamental concepts in which the first concept is of Atom which is the smallest particle of an element that takes place in a chemical reaction. Then there are relative atomic, molecular, and formula masses. The next concept is Avogadro’s number. A device used to measure the exact masses of the isotopes is called a mass spectrometer. The analysis of combustion is also studied and in the end, stoichiometry is the final concept. Then study Molarity, limiting reactant, and yield. Here below, you will find the important MCQs of this chapter. Solve the quiz and prepare for the entrance test.
