I think B sorry if I’m wrong
Explanation
Answer:True
Explanation:
If a substance is pure, it will have exactly the same density as that reported for that particular substance in standard literature or vary within very narrow limits. Hence we can determine the purity of a gold sample by measuring it's density.
To find this answer you take the mass of the carbon in the compound and divide it by the mass of the entire compound, the one closest to 40% is the correct answer.
I will do hexose for you and you can do the rest of them
mass hexose = 6*12 + 12*1 + 6*16 = 72 + 12 + 96 = 180
mass C in hexose = 6 * 12 = 72
% C in hexose = 72/180 * 100% = 40% (This may be your answer unless you have multiple answers for this one)
Answer:
C
