Molarity

How is Molarity calculated?

• Molarity = grams of solute / liters of solution.

• Molarity = moles of solute / liters of solution.

• Molarity = moles of solution / liters of solute.

• Molarity = liters of solute / grams of solution.

What is the Molarity of 186.55 g of sucrose in 250 mL of water?

• 1.00 M

• 1.50 M

• 2.18 M

• 3.00 M

What is the Molarity of a solution if 4 moles of solute are dissolved in 1.5 liters of solution?

• 2.67 M

• 3.00 M

• 2.00 M

• 1.50 M

If you have 2 moles of NaCl in 1 liter of solution, what is the Molarity?

• 1 M

• 2 M

• 0.5 M

• 3 M

If you have a 3M solution and you dilute it to 6 liters, what is the new Molarity?

• 1.0 M

• 1.5 M

• 2.0 M

• 2.5 M

What is the Molarity of a solution if 3 moles of solute are dissolved in 2 liters of solution?

• 1.0 M

• 1.5 M

• 2.0 M

• 2.5 M

What is the unit of Molarity?

• grams per liter (g/L)

• moles per liter (mol/L)

• liters per mole (L/mol)

• moles per cubic meter (mol/m³)

What is the significance of Molarity in chemical reactions?

• Molarity is used to measure the temperature of a solution.

• Molarity helps in determining the color of a solution.

• Molarity is crucial for stoichiometry in chemical reactions, allowing for the calculation of reactants and products.

• Molarity is only important for solid-state reactions.

What is Molarity?

• A measure of the volume of a solution

• A measure of the mass of solute in a solution

• A measure of concentration defined as the number of moles of solute per liter of solution

• A measure of temperature in a solution

How does temperature affect Molarity?

• Molarity remains constant regardless of temperature changes.

• Molarity can change with temperature due to changes in volume.

• Temperature has no effect on the concentration of solutions.

• Molarity increases with temperature due to increased solute solubility.
