Calculation & Formula & Graphing

Front

What is molarity (M)?

Back

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

Front

How do you calculate the volume of a diluted solution?

Back

Use the formula: C1V1 = C2V2, where C1 and V1 are the concentration and volume of the initial solution, and C2 and V2 are the concentration and volume of the diluted solution.

Front

What is the formula to calculate percent by mass?

Back

Percent by mass = (mass of solute / total mass of solution) x 100%.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What does it mean for a solution to be saturated?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more dissolved solute than a saturated solution at the same temperature.

Front

What are significant figures?

Back

Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, zeros between significant digits, and trailing zeros in the decimal portion.

Front

How many significant figures are in the number 0.0520?

Back

There are 3 significant figures in 0.0520.

Front

What is the relationship between temperature and solubility?

Back

Generally, the solubility of solids in liquids increases with temperature, while the solubility of gases decreases.
