If KI K I has a solubility of 140. G g in 100. G g of H2O H 2 O at 20 ∘C ∘ C , how many grams of water are needed to prepare a saturated solution containing 75.0 g g of KI K I ?

53.6g of water are needed

Explanation:

Solubility is the maximum amount that a solvent can dissolve of a particular solute.

100g of Water can dissolve 140g of KI.

That is also the definition of a satured solution: A solution that is dissolved in the maximum amount in a particular amount of solvent.

If there are dissolved 75.0g of KI, the amount of water needed are:

75g KI * (100g water / 140g KI) =

normal fault

A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.  

On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.
