Options

A. 1
B. 2
C. 3
D. 4

Explanation

To find out how many moles are represented by 180 g of glucose, we can follow these steps:

### Step 1: Identify the mass of glucose
The mass of glucose given in the question is 180 grams.

### Step 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

Adding these together:
\[ Molar\ mass\ of\ glucose = 72.06 + 12.096 + 96.00 = 180.156\ g/mol \]
For practical purposes, we can round this to 180 g/mol.

### Step 3: Use the formula to calculate moles
The formula to calculate moles is:
\[ \text{Moles} = \frac{\text{Given mass}}{\text{Molar mass}} \]

### Step 4: Substitute the values into the formula
Substituting the values we have:
\[ \text{Moles} = \frac{180\ g}{180\ g/mol} \]

### Step 5: Perform the calculation
\[ \text{Moles} = 1\ mol \]

### Conclusion
Thus, 180 g of glucose represents 1 mole.
