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:
possible outcomes
Step-by-step explanation:
For any experiment, the sample space of this experiment is the set of all the possible results of the experiment.
In this case we have two spinners. The first has 5 colors, by spinning the spinner you can get up to 5 different results. Therefore the sample space is
For the second spinner there are 3 possible results. By spinning the spinner you can get the numbers 1, 2 or 3. Then .
Then, if the two spinners are rotated, the sample space would be:
possible outcomes.
The tree diagram shown in the attached image shows the 15 possible results
