Explanation:

Step1: Recall density - mass - volume formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume. We can re - arrange it to solve for mass: $m =
ho\times V$.

Step2: Convert volume units

Since $1\ mL=1\ cm^{3}$, the volume $V = 18.26\ mL=18.26\ cm^{3}$.

Step3: Calculate the mass

Given $
ho = 0.7857\ g/cm^{3}$ and $V = 18.26\ cm^{3}$, then $m=
ho\times V=0.7857\ g/cm^{3}\times18.26\ cm^{3}=14.356882\ g$.

Step4: Round to four significant figures

Rounding $14.356882\ g$ to four significant figures gives $14.36\ g$.

Answer:

$14.36\ g$
