Question

Mol stands for what?
The number of particles in 1 mol is named after what scientist/mathematician?
What does ‘molarity’ mean?
What is the formula for finding the ‘molarity’ of a solution?
Find the ‘molarity’ of the following problem:

M= 2.7 mol of salt solution
3.7 L

Answer 1

1) Mol:

The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). ... Thus, for example, one mole of water contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams – and the mean mass of one molecule of water is about 18.015 daltons.

2) Amedeo Avogadro

3) molar concentration

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.

4) Molarity (M) = Moles of solute/ liters of solution

(M) = mol/L

5) M= mol/L

M= 2.7/3.7

M= 0.7297 mol/L

Answer 2

1. In short, 1 mol contains 6.02214076×1023 of the specified particles.

2. Amedeo Avogadro

• Its SI unit is the reciprocal mole, and it is defined as NA = 6.02214076×1023 mol−1. It is named after the Italian scientist Amedeo Avogadro.

3. Molar concentration

• Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.

4. To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters. Note that the volume is in liters of solution and not liters of solvent. When a molarity is reported, the unit is the symbol M and is read as “molar”.

5. M = 0.7297 mol/L
