1. 1.

   A balloon holds 22.01 g of CO₂ (44.01 g/mol) at STP (0 °C, 1 atm, 22.4 L/mol). What volume is that, to 0.01 L, Esme?
2. 2.

   A plant gives off 64 g of O₂ (32 g/mol), measured at STP (0 °C, 1 atm, 22.4 L/mol). What volume is that, to 0.01 L, Jun?
3. 3.

   A box holds 132.03 g of CO₂ (44.01 g/mol) at STP (0 °C, 1 atm, 22.4 L/mol). What volume is that, to 0.01 L, Kira?
4. 4.

   At 0 °C and 100 kPa, about what volume does 2 mol of CO₂ fill, Milo?

   • About 45.4 L
   • About 22.7 L, as for one mole
   • 44.8 L, using 22.4 L/mol from the 1 atm standard
5. 5.

   Ren uses 22.4 L/mol for a balloon of gas at 30 °C. Which reply fits, Noah?

   • Agree, if the gas is carbon dioxide
   • Disagree: warm gas fills more than 22.4 L per mole
   • Agree: 22.4 L/mol works at any temperature
6. 6.

   In respiration, C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O. How much CO₂ at STP comes from 0.25 mol of glucose, Ren?

   • 0.07 L, from 1.5 ÷ 22.4
   • 33.6 L, from 1.5 mol of CO₂
   • 5.6 L, from 0.25 mol of CO₂
7. 7.

   Water forms by 2H₂ + O₂ → 2H₂O, shown as an equation only. How much O₂ at STP reacts with 4 mol of H₂, Tala?

   • 0.09 L, from 2 ÷ 22.4
   • 89.6 L, from 4 mol of O₂
   • 44.8 L, from 2 mol of O₂
8. 8.

   Which fills more space at STP: 64.00 g of O₂ (32.00 g/mol) or 44.01 g of CO₂ (44.01 g/mol), Zee?

   • The O₂: 2 mol, or 44.8 L
   • They match, since both are gases
   • The CO₂, since its molecules are bigger
9. 9.

   A 22.4 L balloon of O₂ and a 22.4 L balloon of CO₂ at STP: which holds more molecules, Ari?

   • The O₂, since its molecules are smaller
   • Neither: each holds 6.022 × 10²³
   • The CO₂, since its molecules are heavier
10. 10.

    Esme says a mole of CO₂ fills more space at STP than a mole of O₂ because CO₂ is heavier. Which reply fits, Bo?

    • Agree: CO₂ fills 44.01 L, its molar mass in liters
    • Disagree: a mole of any gas fills 22.4 L at STP
    • Agree: heavier gas molecules take up more room
