What is molarity?

Back

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

Front

How do you calculate molarity?

Back

Molarity = moles of solute / liters of solution.

Front

What is the formula to find moles from mass?

Back

Moles = mass (g) / molar mass (g/mol).

Front

What is the molar mass of potassium nitrate (KNO3)?

Back

The molar mass of KNO3 is approximately 101.1 g/mol.

Front

How do you convert liters to milliliters?

Back

1 liter = 1000 milliliters.

Front

What is the neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

Front

What is the molarity of a solution if 0.5 moles of solute are dissolved in 2 liters of solution?

Back

Molarity = 0.5 moles / 2 L = 0.25 M.

Front

How do you find the mass of solute needed for a specific molarity?

Back

Mass = molarity (M) x volume (L) x molar mass (g/mol).

Front

What is the molar mass of lithium carbonate (Li2CO3)?

Back

The molar mass of Li2CO3 is approximately 73.89 g/mol.

Front

How do you prepare a diluted solution from a concentrated solution?

Back

Use the formula C1V1 = C2V2, where C is concentration and V is volume.
