water is made up by the elements H20 , salt is made up by the elements NaCl.

May someone please tell me what elements make up fat, proteins , and carbohydartes.

I have a project where i must look at the back of food label and convert the grams to moles and liters. Thanks in advance.

Pure carbohydrates contain carbon, hydrogen, and oxygen atoms, in a 1:2:1 molar ratio, giving the general formula Cn(H2O)n. (This applies only to monosaccharides, see below, although all carbohydrates have the more general formula Cn(H2O)m.)

What does the "n" in Cn(H2O)n mean, please?

if n was 6, then you get:
C6 H12 O6 ...glucose

edit: also...is there really a need to bump your thread every 8 minutes?
