22.4 L
Johnny has an inflatable raft that contains 14.2 moles of nitrogen gas at STP. What is the volume of this raft?
318 liters
What is Avogadro's law?
A direct relationship between the number of moles of a gas and its volume, expressed as V1/n1 = V2/n2
If the number of moles is doubled, what happens to the volume of a gas?
It doubles
At standard temperature and pressure (STP), how much space does 1 mole of any gas take up?
22.4 L
What does Avogadro's law show?
A direct relationship between the number of moles of a gas and its volume
What is Avogadro's law?
Avogadro's law is a tool used to calculate the quantity or volume of a gas.
What is the equation for Avogadro's law?
The equation for Avogadro's law is $V = k \cdot n$ where $V$ is the volume of the gas, $n$ is the number of moles of the gas, and $k$ is a constant.
How is Avogadro's law used to solve problems involving molar volume?
Avogadro's law can be used to calculate the volume of a gas at a given number of moles or the number of moles of a gas at a given volume.
What causes a beach ball to expand when inflated?
When a beach ball is inflated, the particles of the gas (such as nitrogen, oxygen, and carbon dioxide) inside the ball exert pressure on the inside of the ball, causing it to expand.
What are the main components of the breath we inhale and exhale?
The breath we inhale is a mixture of mostly nitrogen and oxygen. The breath we exhale also contains nitrogen, oxygen, and carbon dioxide.
What do the particles of a gas do when they hit the inside of a container?
When the particles of a gas hit the inside of a container, they exert pressure on the inside of that container.
