Understanding Molarity

What does the capital 'M' stand for in the context of molarity?

• Moles

• Milliliters

• Mass per liter

• Moles per liter

How do you convert grams to moles when calculating molarity?

• By using the density of the solution

• By using the molar mass from the periodic table

• By using the temperature of the solution

• By using the volume of the solution

What is the molarity of a solution if 6.75 grams of sodium chloride is dissolved in 452 milliliters of water?

• 0.356 M

• 0.156 M

• 0.256 M

• 0.456 M

When using molarity as a conversion factor, what is the first step in the calculation?

• Calculate the density

• Convert grams to moles

• Convert milliliters to liters

• Find the molar mass

How many grams of potassium hydroxide are needed to make 250 milliliters of a 6.0 M solution?

• 84 grams

• 72 grams

• 56 grams

• 100 grams
