Understanding Avogadro's Law

What does Avogadro's Law state about the relationship between the volume and number of moles of a gas?

• They are equal.

• They are unrelated.

• They are directly proportional.

• They are inversely proportional.

In a graph representing Avogadro's Law, what is plotted on the x-axis?

• Temperature of gas

• Number of moles of gas

• Pressure of gas

• Volume of gas

If the number of moles of a gas is tripled, what happens to the volume according to Avogadro's Law?

• The volume remains the same.

• The volume is halved.

• The volume triples.

• The volume doubles.

What is the formula for Avogadro's Law?

• V1 * P1 = V2 * P2

• V1 / n1 = V2 / n2

• n1 * T1 = n2 * T2

• P1 / T1 = P2 / T2

How do you solve for the final volume (V2) using Avogadro's Law?

• V2 = V1 * n2 / n1

• V2 = V1 * n1 / n2

• V2 = V1 / n1 * n2

• V2 = n1 * n2 / V1

In a problem where 10 moles of gas occupy 250 ml, how much space will 25 moles occupy?

• 500 ml

• 1000 ml

• 250 ml

• 625 ml

If 30 moles of gas occupy 12 L, how many moles will occupy 3 L?

• 5 moles

• 10 moles

• 7.5 moles

• 15 moles

What must be true about the units of volume when using Avogadro's Law?

• They must be in liters.

• They must be in milliliters.

• They must be the same on both sides of the equation.

• They can be different as long as the moles are the same.

In a problem where the volume decreases from 5 L to 0.4 L, what is the initial number of moles if the final number is 5 moles?

• 20 moles

• 62.5 moles

• 10 moles

• 5 moles

When converting milliliters to liters, what operation is performed?

• Subtract 1000

• Multiply by 1000

• Divide by 1000

• Add 1000
