Moles, concentration and volume (Revised)

Front

What is the formula to calculate the volume of a solution?

Back

V = n / C, where V is volume, n is the number of moles, and C is concentration.

Front

Define 'mole' in chemistry.

Back

A mole is a unit of measurement for amount of substance, defined as exactly 6.022 x 10^23 particles (atoms, molecules, etc.).

Front

What is concentration in the context of solutions?

Back

Concentration is the amount of solute present in a given volume of solution, typically expressed in mol/dm³.

Front

How do you convert moles to volume using concentration?

Back

To find the volume, rearrange the formula V = n / C to calculate V when n (moles) and C (concentration) are known.

Front

If you have 15 moles of a substance and a concentration of 5 mol/dm³, what is the volume of the solution?

Back

3 dm³.

Front

If you have 1 mole of sodium hydroxide and a concentration of 2 mol/dm³, what is the volume of the solution?

Back

0.5 dm³.

Front

If you have 3 moles of potassium hydroxide and a concentration of 6 mol/dm³, what is the volume of the solution?

Back

0.5 dm³.

Front

If you have 8 moles of sulfuric acid and a concentration of 4 mol/dm³, what is the volume of the solution?

Back

2 dm³.

Front

If you have 5 moles of magnesium sulfate and a concentration of 5 mol/dm³, what is the volume of the solution?

Back

1 dm³.

Front

What is the relationship between moles, concentration, and volume?

Back

Moles are directly proportional to volume and inversely proportional to concentration.
