How many moles of hydrogen atoms are there in one mole of C6H12O6 molecules? Because different molecules and atoms do not have the same mass, one mole of one thing does not weigh the same as one mole of something else. Highlight to reveal answers and explanations, Questions 1-5 Questions 6-10 Questions 11-15 Questions 16-20 Questions 21-25 Questions 26-30 Questions 31-35 Questions 36-40 Questions 41-45 Questions 46-50, Question 51-53 Questions 54-55 Questions 56-58 Questions 59-61 Questions 62-63 Questions 64-65 Questions 66-68 Questions 69-72  Questions 73-75  Questions 76-78  Questions 79-81 Questions 82-85, , (1) the same molecular structures and the same properties, (2) the same molecular structures and different properties, (3) different molecular structures and the same properties, (4) different molecular structures and different properties. The SI units for molar concentration are mol/m3. Anything can be measured in moles, but it is not practical for most tasks because the value is so massive.
