You have 0.21 moles of Al how many atoms do you have

ZanzabumX [31]

Number of atoms : 1.26 x 10²³

<h3>Further explanation </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

0.21 moles of Al, so n = 0.21

Number of atoms :

$\tt N=0.21\times 6.02\times 10^{23}\\\\N=1.26\times 10^{23}$

The movement of the hydrophobic gas nitrous oxide (n2o) (laughing gas) into a cell is an example of

antoniya [11.8K]

<span>This is an example of diffusion. The nitrous oxide is moving from an area of higher concentration, down the gradient into the cell, which has a lower concentration. Since the cell doesn't have as much N2O as the surrounding environment, the gas will move inside the cell as a way of attaining equilibrium.</span>
