Lead is a toxic metal that affects the central nervous system. A Pb-contaminated water sample contains 0.0011% Pb by mass. 13.6 × 10³ ml water contains 150 mg of Pb.
Given percentage of Pb present in the sample solution is 0.0011%
That means 0.0011 grams of Pb present in the 100g of solution.
So,
= [tex]\frac{0.150\ \text{g Pb} \times 100\ \text{g water}}{0.0011\ \text{g of Pb}}[/tex]
= 13.6 × 10³ g water
The mass per unit volume is called density. Density is represented as D or ρ.
It is expressed as:
[tex]\rho = \frac{m}{V}[/tex]
where,
ρ = Density
m = mass of the object
V = Volume of object
Now put the value in above expression we get
[tex]\rho = \frac{m}{V}[/tex]
[tex]1\ g/ml = \frac{13.6 \times 10^3}{V}[/tex]
V = 13.6 × 10³ ml
Thus from the above conclusion we can say that Lead is a toxic metal that affects the central nervous system. A Pb-contaminated water sample contains 0.0011% Pb by mass. 13.6 × 10³ ml water contains 150 mg of Pb.
