Each mole is 22.4 liters in STP.
So 5.6L is 0.25 moles of O2.
Each mole has 6.022*10^23 molecules(avogadros number)
So 1.505*10^23 molecules of O2 and 3.01*10^23 atoms of oxygen(O).

Hope this helps

forsale [732]

The characteristics of wave are amplitude, speed , frequency and wavelength.

<u>Explanation:</u>

Amplitude is defined as the distance covered by the particles or molecules moving in a wave nature. So the maximum positive and negative peak position is termed as amplitude of the wave.

Every wave forms a series of crests and trough regions. The crest region is the positive amplitude while the trough region is the negative amplitude. The distance between two successive crests and troughs are termed as wavelength.

A single crest and trough forms a complete cycle. So the number of times a cycle is repeated for a given time is known as frequency. Speed is defined as the product of frequency and wavelength of the wave. In other words, speed of a wave is the rate at which the particles are moving a given area per unit time.
