The question asks you to calculate the mass of beryllium based on the given amount in moles.

To solve this:

1. **Given:**
   - Amount of beryllium \( n = 0.0350 \, \text{mol} \)
   - Molar mass of beryllium \( M \approx 9.012 \, \text{g/mol} \) (from periodic table).

2. **Formula:**
   \[
   \text{Mass} = \text{Moles} \times \text{Molar Mass}
   \]
   Substituting the values:
   \[
   \text{Mass} = 0.0350 \, \text{mol} \times 9.012 \, \text{g/mol} = 0.31542 \, \text{g}
   \]

3. **Significant Figures:**
   - Since the given value of moles (0.0350) has 3 significant figures, the mass should also be reported with 3 significant figures.

   Final mass of beryllium: \( 0.315 \, \text{g} \).
