Calculate the ppm of mercury in water in...

Calculate the ppm of mercury in water in given sample contain `30mg` of `Hg` in `500ml` of solution .

Text Solution

Verified by Experts

Parts per million `= ("Mass of solute " xx 10^(6))/("Mass of solution")`
Mass of Hg = 30 mg
Mass of water = 500/1 = `500 g = 50 xx 10^(4) mg`
(density = mass /volume , density of water 1g /ml) `w = (v)/(d)`
Therefore, ppm of mercury `= (30 xx 10^(6))/(50 xx 10^(4))` = 60 ppm of mercury
