NEED HELP ASAP PLEASE!!

Answer 1

`d\approx 17.5 \text{ g/mL}`

Explanation:

We can use the formula

`\text{density}=\frac{\text{mass}}{\text{volume}}`

to calculate the density of the gold in the cylinder:

↓ plugging in the given values

`d = \frac{447\text{ g}}{25.5\text{ mL}}`

↓ evaluating using a calculator

`d\approx 17.5 \text{ g/mL}`
