Answer:
because that the metal dont rust so zinc is coated
Explanation:
It is known that for
, ppm present in 1
are as follows.
1
= 0.494 ppm
So, 150
= ![\frac{150}{1000} mg/m^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B150%7D%7B1000%7D%20mg%2Fm%5E%7B3%7D)
= 0.15 ![mg/m^{3}](https://tex.z-dn.net/?f=mg%2Fm%5E%7B3%7D)
Therefore, calculate the equivalent concentration in ppm as follows.
![0.15 \times 0.494 ppm](https://tex.z-dn.net/?f=0.15%20%5Ctimes%200.494%20ppm)
= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
