The image shows particles of salt dissolved in water. How will the arrangement of salt particles most likely change?
Salt particles will move toward the left through diffusion.
Salt particles will move toward the left through active transport.
Salt particles will move toward the right through diffusion.
Salt particles will move toward the right through active transport.

Hope it may help you

Explanation:

Diffusion can be defined as the movement of particles from a region where there a more concentration of solute to the region having less concentration of the solute.

Here, the salt particles will move from right side of the box to the left side of the box.

This is because the right side has more particle and the left side has less particles so they will move towards the left side.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

the answers would be

the first one and the second one
