What conditions make G always negative? A. G is always negative when the system becomes more random.
B. G is always negative when H is positive and S is negative.
C. G is always negative when the reaction is exothermic.
D. G is always negative when H is negative and S is positive.
the answer is d.

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.

the volume increases

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