Answer

To solve the problem of what is produced from the respiration of 180 grams of sugar (glucose) and 192 grams of oxygen, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- We have 180 grams of glucose (C6H12O6) and 192 grams of oxygen (O2).

2. **Calculate Moles of Glucose**:
- The molecular weight of glucose (C6H12O6) is calculated as follows:
- Carbon (C): 12 g/mol × 6 = 72 g/mol
- Hydrogen (H): 1 g/mol × 12 = 12 g/mol
- Oxygen (O): 16 g/mol × 6 = 96 g/mol
- Total molecular weight of glucose = 72 + 12 + 96 = 180 g/mol
- Now, using the formula for moles:
\[ \text{Number of moles of glucose} = \frac{\text{Weight in grams}}{\text{Molecular weight}} = \frac{180 \text{ g}}{180 \text{ g/mol}} = 1 \text{ mole} \]

3. **Calculate Moles of Oxygen**:
- The molecular weight of oxygen (O2) is:
- Oxygen (O): 16 g/mol × 2 = 32 g/mol
- Now, using the formula for moles:
\[ \text{Number of moles of oxygen} = \frac{192 \text{ g}}{32 \text{ g/mol}} = 6 \text{ moles} \]

4. **Write the Respiration Equation**:
- The balanced equation for the respiration of glucose is:
\[ C6H12O6 + 6 O2 \rightarrow 6 CO2 + 6 H2O + 686 \text{ kcal} \]
- From the equation, 1 mole of glucose reacts with 6 moles of oxygen to produce 6 moles of carbon dioxide and 6 moles of water.

5. **Calculate the Mass of Products**:
- **Mass of Carbon Dioxide (CO2)**:
- Molecular weight of CO2 = 12 (C) + 16×2 (O) = 44 g/mol
- Mass from 6 moles = 6 moles × 44 g/mol = 264 g
- **Mass of Water (H2O)**:
- Molecular weight of H2O = 1×2 (H) + 16 (O) = 18 g/mol
- Mass from 6 moles = 6 moles × 18 g/mol = 108 g

6. **Summarize the Products**:
- The products of the reaction are:
- 264 grams of carbon dioxide (CO2)
- 108 grams of water (H2O)
- 686 kilocalories of energy

### Final Answer:
The products produced from the respiration of 180 grams of sugar and 192 grams of oxygen are:
- 264 grams of carbon dioxide (CO2)
- 108 grams of water (H2O)
- 686 kilocalories of energy
