WebNotes: You will need to look up a pK, for this question and report your answer to 2 decimal places. Your Answer: Answer. Solid CO₂ (0.43 mol) is reacted with CH3MgBr (0.22 mol) in ether solvent. The product of the reaction is isolated in aqueous solution (assume 100% yield) and excess CO₂ is removed. Subsequently, HCI (aq) (0.13 mol) is added. WebAnswer (1 of 2): 1 molecule of C12H22O11 contains 12 + 22 + 11 atoms = 45 atoms 1 mole of C12H22O11 contains 6.022 x 10^23 molecules 1 mole of C12H22O11 contains (6.022 x 10^23 x 45 atoms) 0.025 moles of C12H22O11 contains 6.022 x 10^23 x 45 x 0.025 atoms = 6.77 x 10^23 atoms of C12H22O11
