DO value of a water sample is 6 ppm. Calculate the weight of dissolved oxygen present in 100 kg of water sample.

Text Solution

Verified by Experts

DO value 6 ppm means, `10^(6)`g of water contains 6g of dissolved oxygen. `10^(6)g` water `rarr6g O_(2)`
`"100 kg "(10^(6)g)" water "(6XX10^(5))/(10^(6))=0.6G`
