### Mass Percent Calculation

#### Question:
What is the mass percent of the following solution? 35 g of silver nitrate is mixed with 95 g of water.

#### Options:
- 73% silver nitrate
- 27% silver nitrate
- 2.7% silver nitrate
- 37% silver nitrate

#### Explanation:
To calculate the mass percent of the silver nitrate in the solution, use the formula:

\[ \text{Mass Percent} = \left( \frac{\text{Mass of Solute}}{\text{Mass of Solution}} \right) \times 100 \]

Where:
- The mass of the solute (silver nitrate) = 35 g
- The mass of the solvent (water) = 95 g
- The mass of the solution = Mass of solute + Mass of solvent = 35 g + 95 g = 130 g

Thus,

\[ \text{Mass Percent} = \left( \frac{35 \text{ g}}{130 \text{ g}} \right) \times 100 = 26.92\% \]

Rounding off to the closest whole number gives approximately 27%.

Hence, the correct answer is:
- **27% silver nitrate**
