1. whats the density of a block of gold with a mass of 170g and a volume of 9 cm³?

a. 1530 g/cm³
b. 188 g/cm³
c. .05 g/cm³
d. 18.8 g/cm³

Explanation:

Step1: Recall density formula

The formula for density ($
ho$) is $
ho = \frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 170\,\text{g}$ and $V = 9\,\text{cm}^3$, substitute into the formula: $
ho = \frac{170}{9}$.

Step3: Calculate the result

$\frac{170}{9} \approx 18.8\,\text{g/cm}^3$.

Answer:

D. 18.8 g/cm³
