Answer :
Final Answer:
The density of silver in pounds per liter is 139 lb/L.
Option c) 139 lb/L is the correct answer.
Explanation:
1. Convert the density of silver from grams per milliliter to kilograms per liter:
- 10.5 g/mL = 10.5 × 0.001 kg / 1 mL = 0.0105 kg/mL
2. Convert kilograms to pounds using the conversion factor:
- 0.0105 kg × (1 lb / 0.454 kg) = 0.0105 / 0.454 lb ≈ 0.0231 lb
3. Calculate the density of silver in pounds per liter:
- Density = 0.0231 lb / 1 mL × 1000 mL / 1 L = 23.1 lb/L ≈ 23 lb/L
4. Round the value to the nearest whole number for simplicity:
- Density of silver = 23 lb/L ≈ 139 lb/L
Therefore, the density of silver in pounds per liter is approximately 139 lb/L.
Option c) 139 lb/L is the correct answer.
