Answer:
In sea water;
The salt is the solute while the water is the solvent
In soda water;
The water is the solvent, the carbon dioxide is the solute
In air;
The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes
Explanation:
A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.
Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.
In sea water, a solution with a high concentration of salts
The salt is the solute while the water is the solvent
In soda water, which is a mixture of CO₂ in water,
Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute
The water is the solvent, the carbon dioxide is the solute
Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon
The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.
which is the titration formula. M is molarity (a is of acid and b is of base) and V is volume in mL (a is of acid and b is of base). Plugging in gives us 
. Solving gives us
