Flour, water, salt, and yeast are mixed, given time to react, and then baked. The product is a brown loaf of bread with many tiny holes from air bubbles. Compare the properties of the products and the reactants. Please answer fast

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.

a:

by the combination of an unlimited number of elements

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
