15.37 moles

Explanation:

From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules.

This simply means that 1 mole of C3H8 contains 6.02x10^23 molecules.

Now if 1 mole of C3H8 contains 6.02x10^23 molecules,

Therefore Xmol of C3H8 will contain 9.25x10^24 molecules i.e

Xmol of C3H8 = 9.25x10^24/6.02x10^23

Xmol of C3H8 = 15.37 moles

Therefore, 15.37 moles of C3H8 contains 9.25x10^24 molecules

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
