2. A sample of 2 tsp of sugar, C12H22O11, weighs 9.00 grams. a. How many moles of sugar are in this sample: Show work here: Molar mass of sugar: (12 x 12) + (1 x 22) + (16x11)=(144 +22+176) g/mol =342 g/mol 2 tsp of sugar- 9 grams/342 g/mol = 0.026 mol. b. How many moles of carbon are in this sample? Show work here: c. How many atoms of Carbon in this sample? Show work here: = 1 mol sugar 6.022 x 1023 molecules of sugar (6.022 x 1023 x 0.0026 -1.566 x 1022) 12 x 1. 566 x 1022 =1.8792 x 1023| d. How many total atoms are in this sample? Show work here: Hint: Multiply the number of moles of sugar x Avogadro's number x the total number of atoms in the molecular formula, C12H22O11. 2.
