Explanation:
The given data is as follows.
= 4.60 L,
= 365 mm Hg
= 2.60 L,
= ?
= (20 + 273) K = 293 K,
= (36 + 273) K = 309 K
Since, number of moles of gas are equal so, according to ideal gas equation:
=
=
= 681.03 mm Hg
Thus, we can conclude that new pressure is 681.03 mm Hg.
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>
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:
