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 = 30mg`
Mass of water `=500//1 = 500g = 50 xx 10^(4)mg`
`("As mass" = "Volume"//"density, density of water" 1g//ml)`
Therefore, ppm of mercury `= (30 xx 10^(6))/(50 xx 10^(4)) = 60` ppm of mercury .
