Env. Chem ? re: masses, ppm, and room dimensions
The computer allows 12 tries on any question and I've already exhausted 3 tries. Can someone show this to me, step-by-step? I have only 4 others like it, but my math skills are holding me back.*****
What mass of formaldehyde gas (in grams) must be released from building materials, carpets, etc. in order to produce a concentration of 0.50 ppm of the gas in a room having dimensions of 4.0m X 5.0m X 1.0m?****the computer offered the hint: Calculate vol of room in cubic meters and convert to liters. Use ideal gas law and concentration to calculate amount of formaldehyde. (but I thought I did that!
