A concentration of 0.5 ppm by volume SO2 in the
airis harmful to plant life. What is the percent by volume of
thisconcentration?

Respuesta :

Answer: The percent by volume of [tex]SO_2[/tex] in air is 0.00005%

Explanation:

We are given:

0.5 ppm by volume of [tex]SO_2[/tex] in air. This means that [tex]0.5\mu L[/tex] of sulfur dioxide is present in 1 L of solution (air).

To calculate the percent by volume of sulfur dioxide in air, we use the equation:

[tex]\%\text{ volume of sulfur dioxide in air}=\frac{\text{Volume of }SO_2}{\text{Volume of air}}\times 100[/tex]

We are given:

Volume of [tex]SO_2=0.5\muL=0.5\times 10^{-6}L[/tex]       (Conversion factor:  [tex]1L=10^{6}\mu L[/tex] )

Volume of air = 1 L

Putting values in above equation, we get:

[tex]\%\text{ volume of sulfur dioxide in air}=\frac{0.5\times 10^{-6}\mu L}{1L}\times 100\\\\\%\text{ volume of sulfur dioxide in air}=0.00005\%[/tex]

Hence, the percent by volume of [tex]SO_2[/tex] in air is 0.00005%
