Converting Liters to Moles

What is the formula to convert liters to moles?

• moles = liters × molarity

• moles = liters - molarity

• moles = liters + molarity

• moles = liters ÷ molarity

How many moles are in 2 liters of a gas at STP?

• 2.5 moles

• 1.5 moles

• 0.0893 moles

• 0.5 moles

If you have 1.5 liters of a gas, how many moles do you have?

• 3 moles

• 0.067 moles

• 1.5 moles

• 0.5 moles

What is the molar volume of an ideal gas at STP?

• 30.0 L

• 22.414 L

• 24.5 L

• 18.2 L

How do you calculate the number of moles from volume?

• moles = volume - molar volume

• moles = volume + molar volume

• moles = volume / molar volume

• moles = volume * molar mass

If the molar volume is 22.4 L, how many moles are in 44.8 L?

• 1 mole

• 4 moles

• 2 moles

• 3 moles

What unit is used to measure the amount of substance in moles?

• moles

• grams

• liters

• joules

How does temperature affect the conversion from liters to moles?

• Temperature has no effect on the number of moles in a gas.

• Temperature only affects liquids, not gases.

• Higher temperatures decrease the volume of gas.

• Temperature increases the number of moles in a given volume of gas.

What is the relationship between pressure and volume in gas calculations?

• Increasing volume increases pressure in gas calculations.

• Pressure and volume have no relationship in gas calculations.

• Pressure and volume are inversely proportional in gas calculations.

• Pressure and volume are directly proportional in gas calculations.

If you have 0.5 liters of a gas, how many moles does it represent at STP?

• 0.5 moles

• 0.02232 moles

• 0.0112 moles

• 0.1 moles
