1 mole = 6.022x10²³ of anything. The number 6.022x10²³ is known as Avogadro's number. Avogadro's number is not a mass, it is just a unit of measure. Other units of measure include: 1 pair (2), 1 dozen (12), a baker's dozen (13), et. al. 1 mole is similar in that it simply represents a certain number of things; specifically, Avogadro's number of things.
Since we know 1 mole is not a mass, the first two options can be eliminated. On observing the third option, it cannot be correct because, as we said, 1 mole is equal to Avogadro's number—not an atom of a given substance.

Answer:</h3>
Amount of substance present in Avogadro's number of particles of the substance
N(C): N(H)=n(C): n(H)=6: 10
3×10²¹: x=6: 10
x=5×10²¹
It’s a bad idea for a few hours but it’s
Height of wave - amplitude
Higher the pitch - higher the frequency
Louder - higher the amplitude
bottom of the wave - trough
distance from crest to crest - wave length
top of the wave - crest
