Mercury is highly hazardous and hence its concentration is expressed in the units of ppb (micrograms of Hg present in 1 L of water). Permissible level of Hg in drinking water is 0.0335 ppb . Which of the following is an alternate representation of this concentration?

Options

A $3.35 \times 10^{-2} \mathrm{mg} \mathrm{dm}^{-3}$
B $3.35 \times 10^{-5} \mathrm{mg} \mathrm{dm}^{-3}$
C $3.35 \times 10^{-5} \mathrm{mg} \mathrmm^{-3}$
D $3.35 \times 10^{-4} \mathrm{~g} \mathrm{~L}^{-1}$

Correct answer

B. $3.35 \times 10^{-5} \mathrm{mg} \mathrm{dm}^{-3}$
