Answer: The mass of a gold bar is 0.3864 g.
Step-by-step explanation:
Since we have given that
Volume of gold bar = 50 cm³
Density of gold bar = 19.32 g/cm³
As we know that density is mass divided by volume :
so, it becomes,
\(Mass=\frac{Density}{Volume}\\\\Mass=\frac{19.32}{50}\\\\Mass=0.3864\ g\)
Hence, the mass of a gold bar is 0.3864 g.
