First, determine the number of moles of gold.
Number of moles = 
Given mass of gold =
Molar mass of gold = 196.97 g/mol
Put the values,
Number of moles of gold = 
= 
or 
Now, molarity = 
Put the values, volume of ocean =
Molarity = 
= 
Thus, average molar concentration =
Answer:
it should be momentum if im not mistaken
Thermal energy is atype of movement energy wich is exist in equilibrium.
25.0 g.....................................................
<span>D) Two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.
I HOPE THIS HELPS :)</span>
