How many moles are represented by 160 g of glucose

Explanation

To determine how many moles are represented by 160 g of glucose, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the mass of glucose**:
The mass of glucose given in the problem is 160 g.

2. **Determine the molar mass of glucose**:
The molar mass of glucose (C₆H₁₂O₆) is calculated as follows:
- Carbon (C): 12.01 g/mol × 6 = 72.06 g/mol
- Hydrogen (H): 1.008 g/mol × 12 = 12.096 g/mol
- Oxygen (O): 16.00 g/mol × 6 = 96.00 g/mol
- Total molar mass = 72.06 + 12.096 + 96.00 = 180.156 g/mol (approximately 180 g/mol for simplicity).

3. **Use the formula to calculate moles**:
The number of moles (n) can be calculated using the formula:
\[ n = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
Substituting the values:
\[ n = \frac{160 \text{ g}}{180 \text{ g/mol}} \]

4. **Perform the calculation**:
\[ n = \frac{160}{180} \approx 0.8889 \text{ moles} \]
Rounding this to two decimal places gives approximately 0.89 moles.

5. **Final answer**:
Therefore, 160 g of glucose represents approximately **0.89 moles**.
