The mass and volume of each sample differ from the mass and volume of the other samples. Is it possible for each sample to contain 1 mol of each substance? No, because they have different masses.
No, because they have different volumes.
Yes, if each sample contains 6.02 x 1023 atoms.
Yes, if each sample contains 2 amu.

c: Yes, if each sample contains 6.02 x 1023 atoms.

Explanation:

got it right on the test <3

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.

if you mean hydrogen and oxygen then water is the product
