N which phase(s) of matter are the atoms closely packed but still able to slide past each other? gas
liquid
solid and gas
liquid and solid

I belive its liquid if I'm right because liquids are packed together when they take shape but they are still able to movebrainliest???

Liquid

Explanation:

Please don't jugde me if I got it wrong

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.
