The molar mass of k2SO4 is 174 gram per mole how many k+ ions are there in its one mole of the salt
Correct answer: B. 2NA
- A. 1NA
- B. 2NA
- C. 6NA
- D. 7NA
Explanation
Each k2SO4 molecule contains two potassium ions so one mole of the salt contains 6.02x10^23 molecules of salt hence contains 2 x 6.02x10^23 potassium ions.

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.
