The correct answers to the questions are:
1. Molarity
2. Mole fraction
3. Molality
4. Solvent
5. Solute
<h3>What is molarity? </h3>
This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
Thus, a way to express concentration that provides the moles of solute per liter of solution is molarity
<h3>How to determine the mole of fraction of NaCl</h3>
- Mole of sodium chloride, NaCl = 5 moles
- Mole of sucrose = 4 moles
- Mole of water = 11 moles
- Total moles = 5 + 4 + 11 = 20 moles
- Mole fraction of NaCl =?
Mole fraction = mole / total mole
Mole fraction of NaCl = 5 / 20
Mole fraction of NaCl = 0.25
Thus, the mole fraction of sodium chloride is 0.25
<h3>What is molality?</h3>
This is defined as the mole of solute per unit kilogram of solvent. It can be expressed mathematically as:
Molality = mole / mass (in Kg) of solvent
Thus, the expression of concentration that provides the moles of solute per kilograms of solvent is molality
<h3>What is a solvent?</h3>
A solvent is a substance which disolves other substance.
Thus, if 0.15 grams of sodium chloride dissolves in 1 liter of water, then, the water is called the solvent
<h3>What is a solute?</h3>
This is a substance that dissolves in solvent.
Thus, if 0.15 grams of sodium chloride dissolves in 1 liter of water, then, sodium chloride is the sloute
