The gram atomic mass of an element is 32 g. The number of moles in 48g of element are

Options

A. 0.5mol
B. 2.5 mol
C. 1.5 mol
D. 0.75 mol.

Explanation

To find the number of moles in 48 g of an element with a gram atomic mass of 32 g, we can use the formula:

\[ \text{Number of moles} = \frac{\text{Given mass}}{\text{Atomic mass}} \]

### Step-by-step solution:

1. **Identify the given values**:
- Given mass of the element = 48 g
- Atomic mass of the element = 32 g

2. **Substitute the values into the formula**:
\[ \text{Number of moles} = \frac{48 \text{ g}}{32 \text{ g}} \]

3. **Perform the division**:
\[ \text{Number of moles} = \frac{48}{32} = 1.5 \]

4. **Conclusion**:
The number of moles in 48 g of the element is 1.5 moles.

### Final Answer:
The number of moles in 48 g of the element is **1.5 moles**.
