Question

one tonne of air contains 2*10^-3g carbon as smoke. calculate concentration of carbon in ppm in air. ​

Answer 1

Answer:

Explanation:

Please find the solution to the asked query:

ppm= parts per million (10^-6)  

one tonne of air = 1000 kg = 1,000,000g  

2x10^-3 g of carbon  will be equal  to 0.002g of carbon  

mass(carbon) / mass(air) = 0.002g / 1,000,000g = 0.000000002 = 0.002ppm = 2x10-3ppm
