Molarity and Molality and Mixtures Exam

Front

What is molarity?

Back

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

Front

What is the formula for calculating molarity?

Back

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

Front

What is molality?

Back

Molality (m) is a measure of concentration defined as the number of moles of solute per kilogram of solvent.

Front

What is the formula for calculating molality?

Back

Molality (m) = moles of solute / kilograms of solvent.

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances where the dissolved particles are evenly distributed.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is the universal solvent?

Back

Water is often called the universal solvent because it can dissolve many substances.

Front

How do you calculate the molarity of a solution?

Back

To calculate molarity, divide the number of moles of solute by the volume of the solution in liters.

Front

How do you calculate the molality of a solution?

Back

To calculate molality, divide the number of moles of solute by the mass of the solvent in kilograms.
