Experimental design — practice question

A student has to measure four separate volumes of a solution with high accuracy. The volumes are $10\text{ cm}^3$, $25\text{ cm}^3$, $50\text{ cm}^3$ and $60\text{ cm}^3$. The apparatus provided includes a $25\text{ cm}^3$ pipette. Which of these volumes could be measured with this pipette?

  • A$10\text{ cm}^3$ and $25\text{ cm}^3$
  • B$25\text{ cm}^3$ and $50\text{ cm}^3$
  • C$25\text{ cm}^3$ only
  • D$50\text{ cm}^3$ and $60\text{ cm}^3$
