							Answer:

Therefore, 2 mol of CH3-CHO contains 2×4 = 8 moles of Hydrogen. c) 1 molecule of CH3-CHO contains 1 O-atom. Therefore, 2 mol of CH3-CHO contains 2×1 = 2 moles of Carbon. d) 1 mole of acetaldehyde contains 6.022×10^23 molecules, thus 2 mol will contain 2×6.022×10^23 = 1.2044×10^24 Acetaldehyde molecules
