relative formula mass of glucose? (C6H12O6)

To find the mass of glucose, you must multiply the atomic weight of each of the elements in the molecule by the subscripts in the formula:
[tex] C_{6}=6*(12.01g)=72.06g [/tex]
[tex] H_{12}=12*(1.008g)=12.096g [/tex]
[tex] O_{6}=6*(15.999g)=95.994g [/tex]
Then you add all of them together:
[tex] 72.06g+12.096g+95.994g=180.15g [/tex]
Therefore, the molar weight of glucose is 180.15 grams.
