5. A mobile home has a volume of 100 m³ and a ventilation rate of 0.38 ach (air changes per hour). a) If the concentration of formaldehyde measured in the home is 11 ppm, what is the rate of emission (kg/hr) of formaldehyde from the materials in the home given that [C], = R/kV) where [C], is the indoor concentration, R is the rate of emission, k is the number of air changes per hour, and V is the volume of the room? (Note: this assumes no outdoor source and no indoor sinks.)

![5. A mobile home has a volume of 100 m³ and a ventilation rate of 0.38 ach (air changes
per hour).
a) If the concentration of formaldehyde measured in the home is 11 ppm, what is the rate
of emission (kg/hr) of formaldehyde from the materials in the home given that
[C], = R/kV)
where [C], is the indoor concentration, R is the rate of emission, k is the number of air
changes per hour, and V is the volume of the room? (Note: this assumes no outdoor
source and no indoor sinks.)
b) If new carpeting is purchased and the emission rate triples, how many air changes per
hour are required to maintain a concentration of 5 ppm of formaldehyde?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2e89bee0-d06a-47c0-8c63-0e8ada19220c%2F8d4bcf87-b1fe-45d3-9bec-0af150418df4%2Fdlmel1f_processed.png&w=3840&q=75)
