Dimensions of the room in cm = 2.54 x 12 by 15 x 2.54 by 2.54 x 8.5 = 30.48 by 38.1 by 21.59
Volume of the room in cubic cm = 30.48 x 38.1 x 21.59 cubic cm = 25,072.21 cubic cm
Given that the density of air at room temperature is

, thus the mass of air in the room = 25,072.21 x 0.00118 = 29.59 g = 0.0296 kg
Given that the lethal dose of HCN is approximately 300 mg HCN per kilogram of air when inhaled, thus the <span>amount of HCN that gives the lethal dose in the small laboratory room is given by 300 x 0.0296 =
8.88 mg.</span>
Answer:
(3b + 4) is the greatest common factor
Step-by-step explanation:

<span>g(f(x)) = g(-5x+4) = 4(-5x+4) + 5 = 21-20x</span>
Answer: easy it’s..........
Step-by-step explanation: 26+M
No because 11/12 is not even a whole number, whereas 2 1/3 (ok so not a whole number but above a whole number) is.
