Question

the density of gold is 19.3 g/cm³. what is the volume of a 13 g gold nugget? (density, d = m/v)
○ 25 cm³
○ .67 cm³
○ 1.48 cm³
○ 2.50 cm³

Explanation:

Step1: Recall density formula

$D=\frac{m}{V}$, where $D$ is density, $m$ is mass and $V$ is volume. We need to solve for $V$, so we can re - arrange the formula to $V = \frac{m}{D}$.

Step2: Substitute given values

Given $m = 13\ g$ and $D=19.3\ g/cm^{3}$. Then $V=\frac{13}{19.3}\ cm^{3}$.

Step3: Calculate the volume

$V\approx0.67\ cm^{3}$

Answer:

$0.67\ cm^{3}$
