Answer is in the photo
Explanation:
Have a nice day and if the photo isn’t visible let me know! :)
The mass of the air in the room is 50 kg.
V = lwh = 15.5 ft × 12.5 ft × 8 ft = 1550 ft³
1 ft = 12 in ×
= 30.48 cm
V = 1550 ft³ ×
= 4.39 × 10⁷ cm ³ = 4.39 × 10⁷mL = 4.39 × 10⁴ L
Mass = 4.39 × 10⁴ L ×
= 5.22 × 10⁴ g = 52.2 kg
Note: The answer can have only 1 significant figure, because that is all you gave for the height of the room.
