`DO` value of water sample is 6 ppm. The weight of dissolved oxygen present in `100Kg` of water sample in grams is:

What are the sources of dissolved oxygen in water ?

The values of dissolved oxygen (DO) content in heavily polluted water is less than

The concentration of dissolved oxygen (DO) in cold water can go upto:

If hardness of water sample is 200ppm, then select the incorrect statement:

When temperature increases dissolved oxygen of water

Hardness of water sample is 300 ppm CaCO_3 Hence its molarity is:

With the rise of water temperature, dissolved oxygen:

What weight of glucose dissolved in 100 grams of water will produce the same lowering of vapour pressure as one gram of urea dissolved in 50 grams of water, at the same temperature ?

14.2 g Na_2SO_4 is present in 10^2 kg water. Its concentration in ppm is

Three grams of salt of molecular weight 30 is dissolved in 250 g of water. The molality of the solution is….
