Use the following terms to fill in the blanks:
a. Molality,
b. Mole Fraction,
c. Molarity, Percent by Mass,
d .Unsaturated, Concentration
1. In chemistry, the most commonly used unit of concentration is .
2. The amount of solute (in any measurement unit) divided by the amount of solvent or solution (in any measurement unit) is defined by the basic term of .
3. Dividing the mass of solute by the total mass of solvent and solute will give you the .
4. A method of describing concentration which shows the comparison of moles of solute to moles.

1. Molality.

2. Concentration.

3. Percent by mass.

4.  Mole fraction.

Explanation:

Molarity is the measurement by which the number of moles is measured by a solute. The solution here is one liter respectively.

Concentration is the product which is emerged when the amount of the solute is divided by the amount o the solvent or solution.

Mole fraction refers to the number of component moles divided by the number of the solution moles.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
