a. Calculate the number of moles of C12H22O11 contained in the sample and record

1.202 g C12H22O11 (1 mol / 342.30 g) = 0.0035 mol C12H22O11

b. Calculate the moles of each element in C12H22O11

0.0035 C12H22O11 (12 mol C / 1 mol C12H22O11) = 0.042 mol C

0.0035 C12H22O11 (22 mol H / 1 mol C12H22O11) = 0.077 mol H

0.0035 C12H22O11 (11 mol C / 1 mol C12H22O11) = 0.0385 mol O

c. Calculate the number of atoms of each type in C12H22O11

0.042 mol C (6.022x10^23 atoms / 1 mol) = 2.53x10^22 atoms C

0.077 mol H (6.022x10^23 atoms / 1 mol) = 4.64x10^22 atoms H

0.0385 mol O (6.022x10^23 atoms / 1 mol) = 2.32x10^22 atoms O
