Question

Assume that the NO, concentration in a house with a gas stove is 150 pg/m°. Calculate the equivalent concentration in ppm at STP.

Answer 1

Step-by-step explanation:

It is known that for
`NO_(2)`, ppm present in 1
`mg/m^(3)` are as follows.

1
`(mg)/(m^(3))` = 0.494 ppm

So, 150
`pg/m^(3)` =
`(150)/(1000) mg/m^(3)`

= 0.15
`mg/m^(3)`

Therefore, calculate the equivalent concentration in ppm as follows.

`0.15 * 0.494 ppm`

= 0.074 ppm

Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
