Molarity

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

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 higher temperatures only.

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 in biological processes.

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

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

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 0.10 moles of solute are dissolved in 0.5 liters of solution?

• 0.10 M

• 0.20 M

• 0.30 M

• 0.40 M

What happens to Molarity when you dilute a solution?

• It increases significantly.

• It remains the same.

• It decreases.

• It becomes zero.

What is a dilution in terms of Molarity?

• A dilution is when water is added to a stock solution, decreasing its Molarity.

• A dilution is when a solute is removed from a solution, increasing its Molarity.

• A dilution is when a solution is heated to increase its concentration.

• A dilution is when a solvent is evaporated from a solution, concentrating it.

What is the Molarity of a solution made by dissolving 0.50 moles of NaCl in 400 mL of water?

• 0.75 M

• 1.00 M

• 1.25 M

• 1.50 M
