The formula for glucose is c6h12o6. what is the ratio of carbon atoms to hydrogen atoms in glucose?

From the molecular symbol above, it is evident that per molecule of glucose there are  6 carbon atoms as compared to 12 hydrogen atoms. To be able to determine the ratio between the carbon atoms and hydrogen atoms we simply have to divide the values such that,

           n carbon atoms : n hydrogen atoms

               6: 12

Simplifying,

      1: 2

  1: 2

water or twelve water (H2O) molecules were used to make it.

hope it helps :)

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.
