1. 1.

   A recipe calls for 0.5 mol of glucose. Glucose's molar mass is 180.18 g/mol. How many grams is that, to 0.01 g, Bo?
2. 2.

   A recipe calls for 0.25 mol of table salt. Its molar mass is 58.44 g/mol. How many grams is that, to 0.01 g, Jun?
3. 3.

   Glucose is C₆H₁₂O₆. Using C 12.01, H 1.01 and O 16.00 g/mol, what is its molar mass, Kira?

   • 180.18 g/mol
   • 96 g/mol
   • 29.02 g/mol
4. 4.

   Baking soda is NaHCO₃. Using Na 22.99, H 1.01, C 12.01 and O 16.00 g/mol, what is its molar mass, Luz?

   • 42 g/mol
   • 84.01 g/mol
   • 52.01 g/mol
5. 5.

   Table sugar is C₁₂H₂₂O₁₁. Using C 12.01, H 1.01 and O 16.00 g/mol, what is its molar mass, Milo?

   • 29.02 g/mol
   • 182 g/mol
   • 342.34 g/mol
6. 6.

   Which setup finds the grams in 0.5 mol of glucose, Pia?

   • 0.5 mol × (1 mol ÷ 180.18 g)
   • 0.5 mol ÷ (6.022 × 10²³)
   • 0.5 mol × (180.18 g ÷ 1 mol)
7. 7.

   Which setup finds the grams in 3 mol of table salt, Ren?

   • 3 mol × (1 mol ÷ 58.44 g)
   • 3 mol × (6.022 × 10²³ ÷ 1 mol)
   • 3 mol × (58.44 g ÷ 1 mol)
8. 8.

   Which has the greatest mass: 1 mol of water, 1 mol of salt, or 1 mol of sugar, Tala?

   • 1 mol of water, at 18.02 g
   • They match, since each sample is 1 mol
   • 1 mol of sugar, at 342.34 g
9. 9.

   Which has more mass: 2 mol of water or 0.25 mol of salt, Zee?

   • They match, since mass depends on moles alone
   • 0.25 mol of salt, since salt is heavier
   • 2 mol of water, at 36.04 g
10. 10.

    Which is heavier: 1 mol of CO₂ or 1 mol of water, and by how much, Ari?

    • Neither; equal moles have equal mass
    • CO₂, by 25.99 g
    • Water, by 25.99 g
