On litre of sea water weighs 1050 grams ...

On litre of sea water weighs 1050 grams and contains `6 xx 10^(-3)g` of dissolved oxygen gas. Calculate the concentration of the dissolved oxygen in ppm.

Text Solution

Verified by Experts

Mass of oxygen `(O_(2))=6 xx 10^(-3) g`
Mass of sea water `= 1050 g`
ppm of oxygen `= (25 xx(250 g))/(100)=62.5 ,` Mass of water `= 250-62.5=187.5g`
