Question

The TLV is 350 mg/m³

(Please show calculations)

(c) An experiment is considered in which each student would be required to
evaporate 7 mL of methylene chloride (CH CI). Estimate the average
22
concentration of methylene chloride. Look up the TLV or the TWA for
methylene chloride and consider how the evaporation might be performed.

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.
