Sample Short Answer Questions and Answers
1. Question: Balance the following chemical equation:
_Fe + O2 → Fe2O3_
Answer:
4 Fe + 3 O2 → 2 Fe2O3
2. Question: Calculate the molarity of a solution containing 5.0 grams of NaCl dissolved in 250 mL of solution.
Answer:
Molar mass of NaCl = 58.5 g/mol
Moles of NaCl = 5.0 g / 58.5 g/mol = 0.0855 mol
Molarity (M) = moles of solute / liters of solution = 0.0855 mol / 0.250 L = 0.342 M
