One nanogram is equivalent to how many grams? A) 10⁻⁶ B) 10⁻⁹ C) 10⁻¹² D) 10⁻¹⁵ Correct Answer: B Rationale: The prefix "nano" denotes 10⁻⁹. Therefore, one nanogram (ng) equals 10⁻⁹ grams. A microgram is 10⁻⁶ g, a picogram is 10⁻¹² g, and a femtogram is 10⁻¹⁵ g.

How many milliliters of 0.5 N NaOH are required to make 100 milliliters of 0.2 N NaOH? A) 20 mL B) 40 mL C) 60 mL D) 80 mL Correct Answer: B Rationale: Using the dilution formula C₁V₁ = C₂V₂, where C₁ = 0.5 N, C₂ = 0.2 N, and V₂ = 100 mL: (0.5)(V₁) = (0.2)(100); V₁ = 20/0.5 = 40 mL.

What is the molarity of a solution containing 100 g of NaCl made up to 500 mL with distilled water? (Molecular weight of NaCl ≈ 58 g/mol) A) 1.72 M B) 3.45 M C) 0.86 M D) 6.90 M Correct Answer: B Rationale: Moles of NaCl = 100 g ÷ 58 g/mol = 1.724 mol. Molarity = moles ÷ volume in liters = 1.724 mol ÷ 0.5 L = 3.448 M ≈ 3.45 M.

Which of the following is the correct relationship between absorbance and transmittance? A) A = log(1/T) B) A = -log T C) Both A and B D) A = T × 100 Correct Answer: C Rationale: Absorbance (A) is defined as the negative logarithm of transmittance (T): A = -log T. This is equivalent to A = log(1/T). Both expressions are correct and mathematically identical.

The Beer-Lambert law states that absorbance is directly proportional to: A) Concentration only B) Path length only C) Both concentration and path length D) Neither concentration nor path length Correct Answer: C Rationale: The Beer-Lambert law is expressed as A = εbc, where A is absorbance, ε is the molar absorptivity, b is the path length, and c is the concentration. Absorbance is directly proportional to both the concentration of the absorbing species and the path length of the light through the sample.
