Exploring Dilution and Molarity Concepts

What remains constant when tasting different amounts of the same sugar solution?

• The volume of solution

• The sweetness level

• The temperature of the solution

• The color of the solution

Which has more grams of sugar: a teaspoon or a large glass of the same sugar solution?

• Cannot be determined

• Teaspoon

• Large glass

• Both have equal sugar

What happens to the molarity of a solution when it is diluted with water?

• Increases

• Decreases

• Stays the same

• Becomes zero

After adding water to a sugar solution, the solution tastes less sweet because:

• The concentration of sugar decreases

• More sugar is produced

• The volume decreases

• The moles of sugar decrease

How do you calculate the new molarity after dilution?

• Multiply the original moles by the new liters

• Divide the new moles by the original liters

• Divide the original moles by the new liters

• Divide the new moles by the new liters

What is required to calculate the molarity of a solution?

• Volume of solute and solvent

• Mass of solute and solvent

• Moles of solute and volume of solution

• Density of solute and solvent

What volume of 3.15 M NaOH is needed to prepare 250 mL of 0.15 M NaOH?

• 0.0119 liters

• 0.150 liters

• 3.15 liters

• 0.250 liters

How much water is added to achieve the final volume in the dilution process?

• 0.0119 liters

• 11.9 milliliters

• 250 milliliters

• 238.1 milliliters

What stays constant during the dilution of a sodium hydroxide solution?

• Volume of solution

• Color of the solution

• Moles of sodium hydroxide

• Concentration of solution

In the dilution of sodium hydroxide, what is the final molarity of the solution?

• 0.250 M

• 0.15 M

• 3.15 M

• 1.00 M
