How many times does the mean free path of nitrogen molecules exceed the mean distance between the molecules under standard conditions ?

Algae are known to reproduce asexually by variety of spores under different environmental conditions. Name these spores and the conditions under which they are produced. Asexual reproduction in algae is very common mean of reproduction.

An acoustic wave alphaagates through nitrogen under standard conditions. At what frequency will the wavelength be equal to the mean free path of the gas molecules ?

Find the mean free path of gas molecules under standard conditions if the Van der Waals constant of this gas is equal to b = 40 ml//mol .

Find the mean free path and the mean time interval between successive collisions of gaseous nitrogen molecules (a) under standard conditions , (b) at temperature t = 0 ^@C and pressure p = 1.0 nPa (such a pressure can be reached by means of contemporary vacuum pumps).

When we say that a reaction takes place at standard condition, we mean
