To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched; this aims to foster active technical exchanges while also providing financial rewards to users. 【Daily Question】 (Single-choice question) When calibrating a pipette, the difference between two calibrations must not exceed ( ). A 0.01mL B 0.02mL C 0.05mL D 0.1mL Correct answer: B. Reply with your answer in the comments; answering correctly earns you +2 wealth points. Getting all answers right grants an additional +3 to +8 wealth points. Those who provide thorough analyses and explanations for the questions or answers, or include detailed calculation processes, will receive extra wealth points as a reward. If your answer is correct and your analysis is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions. Note: We will close this post after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation.
