Final answer:
The volume of Emily's silver necklace, with a mass of 150 grams and using the density of silver (10.49 g/cm³), is approximately 14.30 cm³ or 14.30 mL. The correct answer is B. 14.29 mL.
Step-by-step explanation:
To calculate the volume of Emily's silver necklace, we need to use the density formula, which relates mass, volume, and density:
Density formula:
Density (d) = Mass (m) / Volume (V)
Silver has a known density which is approximately 10.49 g/cm³. Given that the mass (m) of the necklace is 150 grams, we can rearrange the formula to solve for volume (V), yielding:
Volume calculation:
Volume (V) = Mass (m) / Density (d) = 150 g / 10.49 g/cm³
After performing the division, we find that the volume of the necklace is approximately:
14.30 cm³, which can also be written as 14.30 mL, since 1 cm³ is equivalent to 1 mL.
Thus, the correct answer to what is the volume of this necklace is B. 14.29 mL.
