Expert Solution
Step 1 Introduction

Methylene chloride (CH2CI2): to understand the recommended exposure limits- Threshold Limit Value (TLV) or the Time-Weighted Average (TWA), to ensure safe handling practices.

To estimate the average concentration of methylene chloride that a student might be exposed to during the evaporation of 7 mL of this chemical.

In this answer, we will use the TLV for methylene chloride to make this estimation & consider the appropriate measures to minimize exposure during the evaporation process.
