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 the number of grams needed for a specific molarity?

Back

To calculate grams needed: grams = molarity (M) × volume (L) × molar mass (g/mol).

Front

What is the molar mass of AgNO3?

Back

The molar mass of AgNO3 (Silver Nitrate) is approximately 169.87 g/mol.

Front

What does a solution consist of?

Back

A solution consists of a solute (substance being dissolved) and a solvent (substance doing the dissolving).

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that dissolves the solute.

Front

What is chromatography used for?

Back

Chromatography is a technique used to separate mixtures into their individual components.

Front

What does it mean if a solute is 'least soluble'?

Back

A 'least soluble' solute does not move far from the start point in chromatography, indicating it has low affinity for the solvent.

Front

What is a colloid?

Back

A colloid is a mixture where tiny particles of one substance are dispersed throughout another substance.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is one in which the components are not uniformly distributed, and different parts can be seen.

Front

What is a solution?

Back

A solution is a homogeneous mixture where the composition is uniform throughout.
