    Chemistry Need help with this threshold limit value (TLV) chemistry problem

    I think the unsettling part is what gets me...I think I was expecting something between 1 and 10 for an "over the TLV" value. Seems the issue is in the problem itself--whoever wrote it must not value safety! Thank you for everything!

    Also, thank you for the advice...I'm still second guessing myself though...mayby e I'm second guessing the problem itself because the amount is so high compared to the safe level. My apologies for asking so many questions of reassurance, I'm just really not confident at all.

    Chemistry Need help with this threshold limit value (TLV) chemistry problem

    Maybe I'm just overthinking this thing? My problem is that I'm not the best with significant figures or scientific notation so I always second guess myself. I'm going to go with "there's too much of this vaporized substance in the room" as my answer...if that's wrong, do I need to convert...

    Chemistry Need help with this threshold limit value (TLV) chemistry problem

    So I'm one step short here but have done all of the other work? I'm just confused and frustrated...do I just have to convert the measurement or is it more about just answering that the people in the room need to evacuate?

    So am I right here or should I revisit something in the problem?

    2119 is greater than 0.66 by a country mile. Did I do the math right in the steps though to get what the problem asked? I'm just confused because 0.66 is so much smaller than a 2119. Something tells me there was a miscalculation in there but I've checked it three times and it always comes out...

    What "feels wrong" is that the answer is four digits. 0.66 vs 2119 and change. I'm not the best with sig figs and am not sure how they'd help in calculating here. It just feels like the concentration here is a LOT more than what they say here. What step am I missing?

    I'm getting 2119.36 for the concentration of mg/cubic meter of this substance...it just feels wrong though. Steps I followed: First, I figured out how many grams of the substance there were using the density formula, then saw how many were present per cubic meter after calculating the volume...
