CFU 6.6 Concentration, Molarity, Dilutions (Flashcardizz, 12-17)

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to lower the concentration of solute per solvent.

Front

When a solvent contains as much of the solute as it can hold, the solution is said to be:

Back

Saturated.

Front

What is the formula for calculating molarity?

Back

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

Front

What is the molarity of a solution containing 0.5 moles of solute in 2 liters of solution?

Back

0.25 M.

Front

What is an unsaturated solution?

Back

A solution where more solute can still be dissolved at the given temperature.

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can be dissolved at a given temperature.

Front

What is the molar mass of NaCl?

Back

58.45 g/mol.

Front

How do you calculate the number of moles from grams?

Back

Number of moles = mass (g) / molar mass (g/mol).

Front

What is the volume of a 0.20 M solution that contains 0.30 moles of Na2SO4?

Back

1.5 L.

Front

What is the molarity of 4 g of NaCl in 3.8 L of solution?

Back

0.018 M.
