Question

If the legal limit for human exposure to CO in the work place is 35 ppm. Assuming that the density of air is 1.3 g/L, how many grams of CO are in 1.0 L of air at the maximum allowable concentration​

Answer 1

Explanation:

Given that

Exposure limit =35 ppm=35 mg/L

Density of air =1.3 g/L

Volume of air =1.0 g/L

Mass of air =1.3 gL

−1

×1.0L=1.3 g

Mass of CO in 1.3 g air =1.3×35 mg/L

=45.5 mg/L

=45.5×10

−3

g/L

=45.5×10

−6

g/mL

=4.55×10

−5

g in per mL air
