i) 6 x 10²³ atoms of copper indicates 1 mole
then, 12 x 10²³ atoms indicate 2 moles of copper
ii) Number of moles = 27.95/56 = 0.5 moles of Iron
iii)6 x 10²³ molecules of CO₂ means 1 mole
then, 1.5 x 10²³ molecules indicate 0.25 moles of CO₂
then, 12 x 10²³ atoms indicate 2 moles of copper
ii) Number of moles = 27.95/56 = 0.5 moles of Iron
iii)6 x 10²³ molecules of CO₂ means 1 mole
then, 1.5 x 10²³ molecules indicate 0.25 moles of CO₂
