Un recipiente contiene 2,5 moles de gas propano. Calcula, utilizando la definición de mol, cuántas moléculas de propano (C3H8) contiene ese recipiente.

POR FAVOR NO LO ENTIENDO Y CON SUS OPERACIONES PLISS

1.505*10^{24}  molecules

Explanation:

The number of molecules is independent of the subtance, and only depends on the number of moles.

To calculate the number of molecules in a substance with n moles you use the following formula:

m: number of molecules

NA: Avogadro's number = 6.02*10^23 molecules/mol

n: moles of the substance = 2.5 mol

You replace the values of n and NA in the equation for m and you obtain:

hence, the number of molecules is 1.505*10^24

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
