1. Hummingbirds eat approximately 43.0 g of sugar water per day How many moles of carbon dioxide are released daily by a hummingbird's respiration? C_12H_22O_11 + 12O_2 > 12CO_2 + 11H_2O

1.507 moles of CO₂ are released daily by a hummingbird's respiration

Explanation:

The reaction of production of carbon dioxide and water from sugar is:

C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O

Where 1 mole of sugar produce 12 moles of CO₂

Molar mass of sugar (To convert the mass to moles) is:

12C = 12ₓ12.01g/mol = 144.12g/mol

22H = 22ₓ1.01g/mol = 22.22g/mol

11O = 11ₓ16g/mol = 176g/mol

144.12 + 22.22 + 176 = 342.34g/mol

Thus, moles of 43.0g of sugar are:

43.0g ₓ (1mol / 342.34g) = 0.1256 moles of sugar.

As 1 mole of sugar produce 12 moles of CO₂:

0.1256 moles of sugar ₓ (12 moles CO₂ / 1 mol sugar) =
