The number of neutrons in H2SO4 are _:
Correct answer: C. 48
- A. 5
- B. 49
- C. 48
- D. 44
Explanation
Option CAtomic mass of H2SO4= 1×2+32+16× 4 = 98Atomic number of H2SO4= 2+16+32 = 50Formula:- number of neutrons = Atomic mass - Atomic numbern=( A- Z)n =98-50n= 48 Ans

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.
