A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution,the_______ is water.
A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the ________is sodium chloride.
If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the ________of sodium chloride would be 0.25.
A way to express concentration that provides the moles of solute per liter of solution is _______-.
Solvent
Mole fraction
solute
pH
Molarity
Molality

Answer 1

The concentration of a solution can be expressed as molality when considering moles of solute per kilogram of solvent, and as molarity when considering moles per liter of solution. In a water and sodium chloride mixture, water is the solvent and sodium chloride is the solute.

Step-by-step explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is molality.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the solvent is water.

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.

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.

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

Answer 2

Molality, Solvent, Solute, Mole fraction, Molarity.

Step-by-step 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.
