that's far much less confusing than you think of. There are 12 moles of C, 22 moles of H, and 11 moles of O in a million mol of sucrose. submit to in techniques that a "mole" is only various atoms, and the chemical formulation only shows the proportions of those atoms mandatory for the compound. It gets somewhat extra complicated once you should start up calculating mass, yet moles is easy.

1 mole = 6.022^23 molecules, so....
2.05^22 molec x (1 mol / 6.022^23 molec) = .0340418
so with Sig-figs, the answer is .034 mol
hope this helps =)

take (2.05x10^22)/ (6.022*10^23).
That is your answer
