Calculate the 8-hour time-weighted average (TWA) of worker exposure based on the information provided below.

In the facility, there are a group of workers that paint and coat parts.In the paint and coating department, the process uses a chemical called calcium sulfate.An air monitor has been set up to collect contaminant concentrations during an 8-hour work period.Perform the calculations identified below from the samples collected and the exposure concentrations, to determine the TLV-TWA average exposure for the 40-hour workweek. Blank 1

Calculate to one decimal point include the unit of measurement i.e., 14.6 mg/m³

In preparation for continuing sampling, you will need to learn to calculate air volumes. Perform the calculations identified below. Show your work neatly and clearly in a manner like the examples provided in Lesson 2 (i.e., write the formula, define each variable in the formula, show steps of your calculations).

What is the total volume of air sampled if a pump moves 540 cc of air per minute over a time span of 6.1 hours? Calculate the answer (no decimal place) and include the unit of measurement, i.e., 1,100 ml.
