9 Molarity and Titrations Flashcard

Front

What is molarity?

Back

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

Front

How do you calculate molarity?

Back

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

Front

What is the molar mass of NaOH?

Back

The molar mass of NaOH (sodium hydroxide) is 40 g/mol.

Front

Calculate the molarity of a solution containing 10 grams of NaOH in 500 mL of solution.

Back

0.5 M

Front

If 0.5 moles of solute is dissolved in 250 mL of solution, what is the molarity?

Back

2 M

Front

What is the formula for dilution?

Back

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

Front

What volume of 0.5 M HCl is required to completely neutralize 25 mL of 1 M NaOH?

Back

50 mL

Front

What is the neutralization reaction between HCl and NaOH?

Back

HCl + NaOH → NaCl + H2O (water) is the neutralization reaction.

Front

What volume of 0.1 M HCl is required to completely neutralize 100 mL of 0.2 M NaOH?

Back

200 mL

Front

What is the molarity of a solution prepared by diluting 50 mL of 4 M solution to a final volume of 200 mL?

Back

1 M
