What is molarity?

Back

Molarity (M) is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution.

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What happens to a reaction at equilibrium when heat is added?

Back

The reaction shifts to the right, towards the products, if the reaction is endothermic.

Front

What is the effect of removing a reactant on a chemical equilibrium?

Back

Removing a reactant shifts the equilibrium to the left, towards the reactants.

Front

What is a concentrated solution?

Back

A concentrated solution has a high amount of solute relative to the amount of solvent.

Front

What is a dilute solution?

Back

A dilute solution has a low amount of solute relative to the amount of solvent.

What is the molar mass of CuSO4?

Back

The molar mass of CuSO4 (Copper(II) sulfate) is 159.60 g/mol.

Front

If 25 mL of a 2M solution is diluted to 500 mL, what is the new concentration?

Back

The new concentration is 0.1 M.

Front

What is Le Chatelier's principle?

Back

Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

What happens to the equilibrium when fluoride ions (F-) are removed?

Back

The equilibrium shifts to the right, towards the products.
