Question
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?
Options
A.4.55 × 10−5 g
B.3.5 × 10−5 g
C.2.69 × 10−5 g
D.7.2 × 10−5 g
Solution
Mass of CO =$\frac{35}{10^{6}} \times 1.3 = 4.55 \times 10^{- 5}\text{ g}$
