Question

1. a goldsmith has a gold bar with a volume of 200 cm³. if the density of gold is 19.3 g/cm³, what is the mass of the gold bar?

Explanation:

Step1: Recall density-mass formula

Density formula: $
ho = \frac{m}{V}$, rearranged to $m =
ho \times V$

Step2: Substitute given values

$
ho = 19.3\ \text{g/cm}^3$, $V = 200\ \text{cm}^3$
$m = 19.3 \times 200$

Step3: Calculate the mass

$m = 3860$

Answer:

$3860\ \text{g}$
