<h3>What is Density?</h3>
Density is the mass of a substance per unit volume.
Where
ρ = density of the substance
m = mass of the substance and
V = volume of the substance
Here, ρ = 48 μg/m³
Volume = 13 ft x 13.5 ft x 19.5 ft
1 ft = 0.3408 m
V = (13 x 0.3408 m) x (13.5 x 0.3408 m) x (19.5 x 0.3408 m)
= 135.46 m³
m = ρ x V
= 48 μg/m³ x 135.46 m³
= 6502.08 μg
= 6502.08 x 10⁻⁶ g
=0.006502g
Hence, The mass of carbon monoxide present in the room is 0.006502 g.

Answer:
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
