Answer:

Sandstone aquifer

Explanation:

Groundwater is essentially water which is present under the earth's surface and stored in structures called aquifers.

Aquifers are structures that are made of unconsolidated materials (like sand, gravel, slit) or rocks which have the appropriate porosity and permeability for water to flow through. Sandstone aquifers are the most widespread and have the appropriate pore size to trap bacteria in contaminated groundwater. Hence, sewage from a ruptured septic tank can sometimes be naturally purified by flowing for a relatively short distance through a sandstone aquifer.

<h2>Answer:</h2>

An Aquifer

<h2>Explanation:</h2>

An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials like gravel, sand, or silt. The most common aquifers are unconsolidated sands and gravels, permeable sedimentary rocks such as sandstones or limestones and heavily fractured volcanic and crystalline rocks. All of these aquifers can be used for the purification of groundwater contaminated by sewage from a ruptured septic tank.

How many moles of KF would need to be added to 2500 ml of water to make 1.2 M solution?
Oduvanchick [21]

The number of moles of KF needed to prepare the solution is 3 moles

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of KF </h3>
  • Volume = 2500 mL = 2500 / 1000 = 2.5 L
  • Molarity = 1.2 M
  • Mole of KF =?

Molarity = mole / Volume

1.2 = mole of KF / 2.5

Cross multiply

Mole of KF = 1.2 × 2.5

Mole of KF = 3 moles
