we know the more legal formula for glucose is six C six, vegetable or six. Therefore, each molecule contain six carbon atom to L a hydrogen atom along with six oxygen atom. Consider a sample off glucose. The number off carbon Artem are one point 250 into 10 days to Part 21 car. When Adams from the molecular formula, there are six carbon atoms with 12 hydrogen atoms calculating the number off hydrogen items, which turns out to be 2.500 into 10 days to par 21. Hydrogen atoms next from the molecular formula off blue cause. It contains a daughter off six. Carbon atom, calculating the number off molecules off glucose. Present as shown, the number off molecules turns out to be 2.83 into 10 days to about 20 molecules. Four. Options see over here one moon off any substance contained. 6.2 into 10 days. Survive 23 Adams. Therefore, one mole off glucose will also contain the same number off atoms or molecules giving US number off moves off glucose by unitary method as three point 460 into 10 days to part negative for for option D. We need to get We have the molar mass off. Luke was as 180 Van Matloff. Lucas will have the same old Amos from that we can deter mined the mask off glucose glucose sample, which turns out to be 0.0 6 to 8 grams.
