The _ study of composition of pure substance in 17th century clearly shows that few elements are components of many substances
Correct answer: B. Quantitative
- A. Qualitative
- B. Quantitative
- C. Both A & B
- D. Extensive
Explanation
The quantitative study of composition refers to the measurement of the amount or proportion of elements present in a substance. In the 17th century, chemists like Robert Boyle and later Antoine Lavoisier focused on determining the exact composition of pure substances, which helped in understanding that a few elements make up many substancesPTB - Pg # 1

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
