Question

Pure silver has a density of 10.49 g/cm3. If you have

42 grams of pure silver, what is the volume of your sample?
Round to four significant digits.
0.2498 cm^3
1.915 cm^3
2.216 cm^3
4.004 cm^3

Answer 1

Answer: Volume of sample is 4.004 cm³

Explanation:

Given: Density of pure silver is 10.49 g/cm³

Mass of silver = 42 grams

To find: The volume of sample

As we know

`\text{ Density }= \frac{\text {Mass }}{\text {Volume }}`

As given in question we have

`10.49 \text { g/}cm^3 = \frac{42 g }{\text {Volume}} \\\\\Rightarrow \text {Volume}= \frac{42g}{10.49\text { g/}cm^3 } \approx 4.0038 \approx 4.004 cm^3`

Hence 4. is the right option

Volume of sample is 4.004 cm³
