Calculate the delta H, delta S, and delta G for the following reaction used in the space shuttle for propulsion at 25degree C4 N2H3CH3(l) + 5 N2O4(l) -> 12 H2O(g) + 9 N2(g) + 4 CO2(g)Is the reaction spontaneous?

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.
