The number of moles of water in 1 kg ice are:
Correct answer: D. 55.5 moles
- A. 50 moles
- B. 100 moles
- C. 1000 moles
- D. 55.5 moles
Explanation
1 mole of water corresponds to 18g. So, to calculate the number of moles of water in 1kg or 1000g of ice (NOTE: The state of the substance does not have an effect in such stoichiometric calculations), 1000 is divided by 18, which comes out to 55.5 moles.

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.
