Zinc will displace copper from a solution of copper sulfate, and magnesium will displace zinc from a solution of zinc
sulfate.
a Write word equations for these two reactions.

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.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

you gotta add the following molecules so we can give u an answer
