- where:
- V is the volume of the gas.
- n is the amount of substance of the gas.
- k is a proportionality constant.
Using Avogadro's Law Aleks
Avogadro’s law also means the ideal gas constant is the same value for all gases, so:
constant = p1V1/T1n1 = P2V2/T2n2
V1/n1 = V2/n2
Usually, within problems, it is clearly stated when gas is at S.T.P. This is usually used within combined gas laws, ideal gas law, as well as problems relating to specific laws (i.e. Boyle's law, Avogadro's law, etc.). Between S.T.P and R.T.P, usually, S.T.P is mainly used within gas law problems especially. Since pressure is kept constant, we can directly compare the moles of gas in the container and volume using Avogadro's law. Since moles of gas and volume are on opposite sides of the ideal gas law, the two variables are directly proportional to one another.
How To Use Avogadro's Number
V1n2 = V2n1
where p is the pressure of a gas, V is volume, T is temperature, and n is number of moles
Examples of Avogadro’s law in Real Life Applications
- As you blow up a football, you are forcing more gas molecules into it. The more molecules, the greater the volume. The basketball inflates.
- As you blow up a balloon, you are forcing more gas molecules into the balloon which would increase the balloon volume and cause them to balloon inflate.
- A flat tire takes up less space than an inflated tire, because it contains less air.
