By dissolving 2 moles of the compound in 1 L of water
Sand is a mixture and rarely is only one compound.
To prepare a 0.01M solution of butanesulphonate, you would weigh out the appropriate amount of butanesulphonate compound needed to achieve a concentration of 0.01 moles per liter in a certain volume of solvent (usually water). You would dissolve the weighed compound in the solvent and then make up the final volume to reach the desired concentration. Finally, you would mix the solution thoroughly to ensure homogeneity.
Gold is an element because it is made up of only one type of atom. It is not a compound, solution, or heterogeneous mixture.
The solution with the largest total ion concentration will be the one that completely dissociates into ions. Therefore, one mole of a strong electrolyte compound like sodium chloride (NaCl) would have the largest total ion concentration, as it dissociates into two ions (Na+ and Cl-) in water. By contrast, one mole of a weak electrolyte compound like acetic acid (CHβCOOH) would not dissociate completely, leading to a lower total ion concentration.

To make a 2 M solution of a compound, you would first need to determine the molar mass of the compound. Once you have the molar mass, you can calculate the amount of compound needed to make the solution by using the formula: moles = Molarity x Volume (in liters). Finally, dissolve the calculated amount of compound in the appropriate volume of solvent to make a 2 M solution.
When one compound dissolves into another compound, it becomes a solution.

Baking soda is a compound composed of the elements sodium, hydrogen, carbon, and oxygen. Therefore, it is neither a solution nor an element.
There are two definitions for the word solution. One is that a solution is the answer to solving a problem, and the second one is a chemical compound that has ionic bonds.
Water is a compound, specifically a chemical compound made up of two hydrogen atoms and one oxygen atom. It is not an element, solution, or heterogeneous mixture.

A colloid. It is not a solution - that would be clear because one compound is dissolved by the other. It is not a suspension - a suspension is solid particles mixed with a liquid
To prepare a 0.1N solution of hyponatrite (Na2S2O4), you would first need to calculate the molar mass of the compound. Then, you would dissolve the calculated mass of hyponatrite in a sufficient amount of water to make a 1 liter solution, as 0.1N corresponds to 0.1 moles per liter.
