A aquifer is the underground layer which is composed of water-bearing rocks. Sandstone, sands, gravel, and other sedimentary rocks are examples of water-bearing rocks. They are permeable and have openings that gases and liquids can pass through. In a water cycle, a water will be added to the aquifer during the precipitation.
Answer: The answer to your question is OD
Hope this helps.
Moles = concentration x volume
we tryna find volume so
volume = moles/concentration
= 3.6/0.3 = 12dm^3
1 liter is 1 dm^3 im pretty sure
so the answer is just 12
-log(1.2x10^-3) = 2.92 = pH
14 - 2.92 = 11.08 = pOH

<h3>Further explanation</h3>
Given
4 moles of Carbon dioxide.
Required
Carbon dioxide molecules
Carbon atoms
Oxygen atoms?
Solution
1 moles = 6.02 x 10²³ particles(molecules, atoms, ions)
1. Carbon dioxide molecules :
= 4 moles x 6.02 x 10²³
= 2.408 x 10²⁴ molecules
2. The number of Carbon atoms
In CO₂, there is 1 atom C, so the number of atoms :
= 1 x 2.408 x 10²⁴
= 2.408 x 10²⁴ atoms
3. The number of Oxygen atoms :
In CO₂, there is 2 atom O, so the number of atoms :
= 2 x 2.408 x 10²⁴
= 4.816 x 10²⁴ atoms
