Q: The number of gm-equivalent of the solute per litre of solution is known as-
  • A. Normality
  • B. Molarity
  • C. Molality
  • D. Mole fraction
Correct Answer: Option A - Normality is defined as the number of gram-equivalent of solute present in one litre of solution. It is a measure of concentration that is particularly useful in acid-base and redox titrations.
