What is molarity (M)?

Back

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution.

Front

How do you calculate the number of moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L).

Front

What is the formula to prepare a specific molarity solution?

Back

To prepare a solution of a specific molarity, dissolve the required mass of solute in enough solvent to make a specific volume of solution.

Front

What is the molecular mass of C6H12O6?

Back

The molecular mass of C6H12O6 (glucose) is 180.0 g/mol.

Front

How do you find the concentration after dilution?

Back

Use the formula: C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume.

Front

What is percent volume concentration?

Back

Percent volume concentration is the volume of solute divided by the total volume of solution, multiplied by 100.

Front

How do you convert mL to L?

Back

To convert mL to L, divide the volume in mL by 1000.

Front

What is the relationship between moles, mass, and molar mass?

Back

Moles = Mass (g) / Molar Mass (g/mol).

Front

If you have 0.5 M NaBr and add water, what happens to the concentration?

Back

The concentration decreases as the volume of the solution increases.

Front

What is the significance of the number of moles in a solution?

Back

The number of moles determines the amount of solute present, which affects the solution's properties and reactions.
