Question

1. what is the mass of gold in 57.9 ml of gold? density of gold is 19.3 g/cm³?

Explanation:

Step1: Recall density formula

Density formula is $
ho = \frac{m}{V}$, so $m =
ho \times V$. Note that $1\ mL = 1\ cm^3$, so $V = 57.9\ cm^3$.

Step2: Substitute values

Given $
ho = 19.3\ g/cm^3$ and $V = 57.9\ cm^3$, calculate $m = 19.3\ g/cm^3 \times 57.9\ cm^3$.

Step3: Perform multiplication

$19.3\times57.9 = 1117.47$.

Answer:

The mass of gold is $1117.47\ g$.
