Molar Volume and Concentration Quiz

What is the formula for calculating molar volume?

• Molar volume = Molar mass - Density

• Molar volume = Molar mass / Density

• Molar volume = Molar mass + Density

• Molar volume = Molar mass * Density

What are the units of molar volume?

• cm^3/mol

• L/mol

• mL/mol

• g/mol

Calculate the molar volume of a gas at STP if the volume is 22.4 L and the number of moles is 1.

• 1 L

• 10 L

• 100 L

• 22.4 L

What is the formula for calculating concentration?

• Amount of solute - Volume of solution

• Amount of solute / Volume of solution

• Amount of solute + Volume of solution

• Amount of solute * Volume of solution

What are the units of concentration?

• grams per liter (g/L)

• moles per kilogram (mol/kg)

• moles per liter (mol/L) or molarity (M)

• parts per million (ppm)

Calculate the concentration of a solution if the volume is 500 mL and the number of moles is 0.25.

• 0.05 M

• 1 M

• 0.5 M

• 0.1 M

What is the formula for calculating molarity?

• Molarity = moles of solute / volume of solution (in liters)

• Molarity = volume of solution / moles of solute

• Molarity = moles of solute + volume of solution

• Molarity = moles of solute * volume of solution

What are the units of molarity?

• kg/L

• g/L

• mol/L

• mol/m^3

Calculate the molarity of a solution if the volume is 1 L and the number of moles is 0.5.

• 0.5 M

• 0.05 M

• 1.5 M

• 0.005 M

What is the molar volume of a gas at STP?

• 22.4 liters/mol

• 1.5 liters/mol

• 50 liters/mol

• 10 liters/mol
