Fill in the blank A(n)is a disturbance that transfersfrom one place to another without transferring.

This if about WAVES fill in the blank and this is science work due today Thanks!!

1 wave 2 energy 3 matter those are the blanks

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.

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
