The mercury content of a stream was believed to be above the minimum considered safe—1 part per billion (ppb) by weight. an anal
shutvik [7]

Answer:

Amount of mercury is 1.0*10⁻⁵ g

Explanation:

<u>Given:</u>

Mercury content of stream = 0.68 ppb

volume of water = 15.0 L

Density of water = 0.998 g/L

<u>To determine:</u>

Amount of mercury in 15.0 L of water

<u>Calculation:</u>

1 ppb = \frac{1\mu g(solute)}{1L(solvent)}

where 1 μg (micro gram) = 10⁻⁶ g

0.68 ppm implies that there is 0.68 *10⁻⁶ g mercury per Liter of water

Therefore, the amount of mercury in 15.0 L water would be:

=\frac{0.68*10^{-6}g\ Hg* 15.0\ L\ water}{1\ L\ water} =1.02*10^{-5}g
