Answer:
2.69 x 10²³ atoms
Explanation:
Given parameters:
Volume of sea water = 2.06mL
number of moles of gold = 0.446moles
unknown:
Number of atoms in the sea water
Solution:
The mole is a convenient unit of measuring quantities of particles. In a mole we have 6.02 x 10²³particles.
The mole can be defined as the amount of a substance contained in Avogadro's number of particles which is 6.02 x 10²³particles.
Here, the particles we want to determine is the number of atoms:
Number of atoms is given as:
Number of gold atoms = number of moles of gold x 6.02 x 10²³
Number of gold atoms = 0.446 x 6.02 x 10²³ = 2.69 x 10²³ atoms

Answer:All the above
Explanation:
Non-ideal solutions are those solutions which do not obey Raoult's law in any conditions.
The molecular interactions of two components that is solute and solvent are different.
If there are two components A and B then the molecular interaction between A-A,B-B would be different from the molecular interactions in A-B .
The enthalpy of mixing and volume of mixing for non-ideal solutions have non zero values.
Enthalpy of mixing can be negative or positive in case of non-ideal solutions. If the enthalpy of mixing is negative so energy has been released upon mixing the two components and if enthalpy of mixing is positive then energy is absorbed upon mixing the two components.
Non-ideal solutions are simply those solutions which are not ideal hence they should not be having the characterstics of ideal solutions.
For ideal solutions the molecular interactions between the two components are equal.
So the molecular interaction between A-A,B-B would be equal to the molecular interaction between A-B. Also the enthalpy of mixing and volume of mixing for ideal solutions are zero hence all the statements provided here are correctly charactersing non-ideal solutions.
