A1.0-ml volume of seawater contains about 4.0 x 10^-12 g of gold. the total volume of ocean water is 1.5 x 1021l .calculate the total amount of gold (in grams) that is present in seawater and the worth of the gold in dollars. with so much gold out there, why hasn't someone become rich by mining gold from the ocean?

Answer is given below.

Explanation:

So, seawater contains of gold

hence seawater contains gold or gold

So, gold =

Seawater contains majorly different kinds of salts e.g. along with gold in very very small amount.

So, purification of seawater is more rigorous and more costlier than extracting gold from ores.

Hence investing money in mining gold from seawater lead to huge loss.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
