DO value of a water sample is 6 ppm. Calculate the weight of dissolved

1.	DO value of a water sample is 6 ppm. Calculate the weight of dissolved oxygen present in 100 kg of water sample.
Answer» SOLUTION :DO value 6 ppm means, 100 G of water contains 6g of dissolved OXYGEN. `10^(6)g " water " to 6g O_2` `100 kg (10^(5)g) " water " to (6 xx 10^(5))/(10^6)=0.6 g ` Amount of dissolved oxygen in water = 0.6 g
