How do you prepare 100 mL of a 20% (v/v) ethanol solution from pure (100%) ethanol?
Answer: A. Add 20 mL of 100% ethanol to a 100 mL volumetric flask and fill to the mark with water
A 20% v/v solution requires 20 mL of ethanol per 100 mL total volume. Add 20 mL of ethanol to a 100 mL volumetric flask and fill to the 100 mL mark with water.
A technician prepares a solution by dissolving 58.44 grams of NaCl (Formula Weight = 58.44 g/mol) in enough water to make a final volume of 1.0 L. What is the molarity (M) of this solution?
Answer: C. 1.0 M
Molarity is defined as moles of solute per liter of solution. First, calculate the number of moles of NaCl: Moles = Mass (g) / Formula Weight (g/mol) = 58.44 g / 58.44 g/mol = 1.0 mole. Since the final volume is 1.0 L, the molarity is 1.0 mole / 1.0 L = 1.0 M.
What equipment is required to accurately prepare a 1.00 M NaCl solution in a volume of exactly 100 mL?
Answer: B. A 100 mL volumetric flask, an analytical balance, and a magnetic stir plate
A volumetric flask provides exact final volume, an analytical balance provides accurate mass measurement — both are required for a 1.00 M concentration with proper significant figures.
A technician prepares a diluted working solution of a hazardous chemical in a spray bottle for daily use. The original stock bottle has a complete GHS label. What is the MINIMUM information required by OSHA on the label for this new 'secondary container'?
Answer: B. The chemical identity and words, pictures, or symbols indicating the hazard.
According to OSHA's Hazard Communication Standard, secondary containers must, at a minimum, be labeled with the identity of the hazardous chemical and general information regarding its hazards using words, pictures, or symbols. While a full GHS label is an option, it is not the minimum requirement.
