Molarity Calculations Worksheet – Practice #1

Front

What is molarity?

Back

Molarity is defined as the number of moles of solute per liter of solution.

Front

How do you calculate the number of liters needed for a specific molarity and moles of solute?

Back

To find the number of liters needed, use the formula: liters = moles of solute / molarity.

Front

What is the formula for calculating molarity?

Back

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

Front

If you have 0.905 moles of KI and a solution concentration of 0.325 M, how many liters of solution do you need?

Back

You need 2.785 liters of the 0.325 M KI solution.

Front

What is the molarity of a solution if 11 moles of NaCl are dissolved in 33 liters of solution?

Back

The molarity of the solution is 0.3 M.

Front

How do you convert grams of a substance to moles?

Back

To convert grams to moles, use the formula: moles = grams / molar mass.

Front

How many liters of a 0.63 M solution would contain 42 g of Al(NO3)3?

Back

You would need 0.31 liters of the 0.63 M solution.

Front

What is the relationship between molarity and the concentration of a solution?

Back

Molarity is a measure of the concentration of a solute in a solution.

Front

If a sweet tea has a molarity of 3.1M, how does it compare to other solutions in terms of sweetness?

Back

A sweet tea with a molarity of 3.1M would be expected to taste the sweetest compared to lower molarity solutions.

Front

What is the significance of the molar mass in molarity calculations?

Back

Molar mass is used to convert grams of a substance to moles, which is essential for calculating molarity.
