Answer:

Molality, Solvent, Solute, Mole fraction, Molarity.

Explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is Molality.  This in the only expression referred to the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solvent is water.  When water is present, it is usually considered the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solute is sodium chloride.  There can be 1 or more solutes in a solution.

If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the Mole fraction of sodium chloride would be 0.25.  The mole fraction is equal to the moles of a substance divided by the total number of moles.

A way to express concentration that provides the moles of solute per liter of solution is Molarity.

Answer:

The answer to your question is 6

Explanation:

Data

              Cu  +  2AgNO₃   ⇒  

To find the answer, count the number of each element in the reactants

Element                Quantity

Copper                        1

Silver                           2

Nitrogen                      1

Oxygen                        6

Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
