Which TWO properties of water make it essential for supporting the
development of life? (Again, there
are TWO answers here, be sure to check
both of them!
Water has all the ingredients needed to
create lite.
Water allows biomolecules (like proteins) to
move around and react with one another.

hydrated.

sry but any answer choices

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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
